It isn’t hard to find a firearms museum that has something special, but what sets the Rock Island Arsenal Museum apart from other military and firearms museums is that it in itself is truly very special. Located at the Rock Island Arsenal in Illinois, the museum occupies the room in Building 60 that once housed Shop B where the Model 1903 Springfield receiver was produced during the First World War.

Today the museum is home to one of the finest collections of small arms in North America, and moreover it is the second oldest U.S. Army Museum in the United States after the West Point Museum. Established on July 4, 1905, the museum has only been closed twice – during World War I and World War II to provide more space for the manufacturing facilities. Today the museum’s collection now includes some 12,000 items in total; with nearly 70 percent of the museum’s firearms on permanent display.

The only downside to displaying a collection of this size is that it isn’t presented in any chronological order, nor is it broken down by nation or even weapon type. Instead the collection features vintage black powder long guns on the wall with modern MAC 10s.

“We’d like to reorganize the collection but it is impossible at the present time,” said Kris Gayman Leinicke, director of the Rock Island Arsenal Museum. “With so many firearms there is simply no way to take everything down and reorganize it without closing the museum for days or weeks.”

The irony in this is that the museum had fairly humble beginnings when 110 years ago Chief of Ordnance Major General William Crozier supplied 15 boxes of ordnance and small arms with the intent to preserve it as a military museum at the Rock Island Arsenal. From those 15 boxes the collection has grown and greatly expanded. Today the collection of small arms is displayed on nearly two full walls with firearms dating back to the American Revolution and continuing to the modern day.

The oldest piece in the collection is believed to be a “wall gun” that features a 1 3/16-inch bore diameter. It is believed this firearm was made between 1775 and 1780 at the Rappahannock Forge in Falmouth, Virginia. It is also one of just five of these wall guns known to exist – the museum also has one other not on display in its collection.

Special attention is paid to the firearms that were produced at the Rock Island Arsenal and this includes a Model 1903 Springfield with serial number 1. While this rifle was designed and produced by the Springfield Armory this example is one of the first 18,000 rifles produced as the rod-bayonet type. Under the orders of then President Theodore Roosevelt on January 4, 1905 the production of this model was halted and a new knife-bayonet version was produced.

According to the museum’s records this example has the serial number 1, and was likely fabricated on December 20, 1904 but has the stock dated as 1905 and marked “CN/1905.” This cartouche actually indicates that the rifle was inspected in the fiscal year 1905. It has been in the museum’s collection ever since it passed this inspection.

From the very old to the new the museum also has on display a very rare example of the General Officers M15 Pistol, which was designed at the Rodman Laboratories at the Rock Island Arsenal. Only 1,004 of these were produced on the island from 1972 to 1974 and these were designed to replace the Colt “Model M” .32 and .380 caliber “pocket pistols” that had been issued to General Officers since 1941.

These pistols were all rebuilt Model 1911A1 pistols that were produced by the same armorers at the Rock Island Arsenal, but featured a shortened barrel and slide, distinctive horizontal grooves on the back grip and checkering on the front grip strap.

The collection also includes several M1919 .30 caliber Browning machine guns. The Rock Island Arsenal produced these beginning in 1938 with the M1919A4 air cooled confirmation being the most common model to pass through the armories and production continued throughout World War II.

Another item developed at the Arsenal was the “Brunton Bump,” that was designed to allow left-handed shooters to fire an M16/M4 without having the shell casing fly across the shooters’ face. It was designed by Loren H. Brunton of the small arms branch at the Rock Island Arsenal, and he even holds two patents for the design of this unique and very necessary feature.

American Small Arms

The Rock Island Arsenal Museum is of course devoted to the history of American small arms. Housed in its collection are some truly unique pieces and these include three of the only known examples of the Pederson Device, which was developed during the First World War to convert the Model 1903 rifle from a bolt action into a semiautomatic rifle.

Known officially as the “Automatic Pistol, Caliber .30 Model of 1918” in an attempt to keep the design and manufacture a secret, it utilized a special 40-round magazine that held the .30 caliber pistol cartridge. The rifle had to be slightly modified to use the Pederson Device and was re-designated as the Model 1903 Mark I.

“These are the holy grail for our collection,” said Eric Kramer, public affairs director for the Rock Island Arsenal. “I know of only three others that are in private collections but we are fortunate to have three in our collection.”

The Rock Island Arsenal Museum also features several notable prototypes including a Model 1919 submachine gun that was built by the Auto-Ordnance Corporation in 1919. The example, serial number 6, is one of just a handful of known examples of the prototypes of the firearm that would go on to become the Thompson submachine gun.

While Eugene Stoner’s AR-15, later the M16, was not designed or produced at the Rock Island Arsenal the museum does have several notable pieces in its collection, which showcase the development and evolution of this firearm from the 1960s to the modern M4 versions.

The collection also features numerous versions of the M79 grenade launcher and examples of the MAC 10/11; but a visitor favorite remains a gold plated M60 machine gun that marked the end of the firearm’s production run. It is made of unserviceable parts and thus is one of the firearms in the collection that couldn’t actually fire, and attempts to remove it from permanent display have created a problem. “People keep asking to see the ‘gold gun,” said Leinicke.

International Weapons

The collection is not limited to American firepower – and the museum has several notable pieces on display including a mid-19th century Japanese matchlock to several variations of the British Sten gun. Among the standout pieces of international firearms are those that were developed by America’s enemies and rivals in the 20th century.

These include several examples of German firearms from both World Wars including variations of the MP-18/I and MP-28/II as well as the MP40, MG34 and MG42 machine guns. The most impressive standouts in the German collection is that the museum features three versions of the FG42 (Fallschirmjägergewehr 42 or “paratrooper rifle 42”), which was one of the most advanced small arm designs of the Second World War. Only some 6,000 of these were produced during the war and three are now in the museum’s collection.

In addition to the FG42 the museum also has three MP44/StG44 “Sturmgewehr” examples in the collection. These were the first true “assault rifles” developed and had a major impact on modern infantry small arms development. While it has been argued that the AK47 was not a copy of the StG44 – the weapons have different mechanisms – it is true that the Soviets closely examined the thousands of captured weapons and these likely did play a role in Soviet Cold War small arms development.

The Rock Island Arsenal has several notable examples of these Soviet weapons including AK47 variations, but also other small arms including the PPSh41, DP28 and SKS.

With so many firearms it is hard to take in everything on one visit, but even to Leinicke it is really more than just a museum. “This is really a library of small arms as much as it is just a really good museum.”

Beyond the Museum

The museum is just one small component of the Rock Island Arsenal – the 946 acre island located on the Mississippi River. In fact the history of the government presence here goes back to 1816 with the construction of Fort Armstrong, which was one of the first western frontier defenses that were erected by the U.S. Army after the War of 1812. The Island later served as a prisoner of war camp during the American Civil War. Today the island is the final resting place for some 2,000 Confederate prisoners.

Since the 1880s, the Rock Island Arsenal, which is largest government-owned weapons manufacturing armory in the country, has produced various military equipment and ordnance including the M198 and M119 towed howitzers, as well as the Anglo-American Liberty Mark VIII tanks that were manufactured just after the First World War. Unfortunately none of these first American-made tanks has survived to the modern day, but the Rock Island Arsenal does have several other large pieces on display at the Memorial Field. In total 31 ordnance systems are on permanent display and these include an M119 howitzer, M51 anti-aircraft gun, an M50 anti-tank gun and even an M65 Atomic Cannon. This is the islands way of showing off its “big guns.”

U.S. Rifle, Caliber .30 Model of 1903

The U.S. M1903 Rifle was designed and adopted to replace the Krag-Jorgensen rifle and its .30-40 cartridge. Adopted on June 19, 1903, the M1903 Rifle was chambered for the Model of 1903, .30 Government Cartridge (.30-03), which had a 220-grain round-nose projectile. The Model of 1903 Rifle was only in service a short period of time before some changes were made. One of the most prominent upgrades was the rechambering for the improved Model of 1906 cartridge, which had a lighter, spitzer-type projectile and an improved powder. A newly designed M1905 rear sight was also added. The rifles were manufactured by Springfield Armory and Rock Island Arsenal from 1903 until 1914. Production was quickly resumed during 1917 with the U.S. entry into World War I.

The M1903 Rifle in .30-06 caliber remained the standard service weapon of the U.S. until the adoption of the M1 Rifle in 1936. During World War II, production of the M1 Garand was not able to keep up with the wartime demand. Thus, Remington Arms was awarded a contract to resume manufacture of the M1903 Rifle. During production, there were many new features implemented into the original design of the ’03 rifle to speed up production. These rifles were designated as the M1903 (Modified). Subsequently, more improvements were made resulting in the M1903-A3 model, which was adopted on May 21, 1942. The 03-A3 had many stamped parts, a new receiver mounted aperture rear sight and a longer hand guard. The L.C. Smith & Corona Company was awarded a contract in February of 1942 to supplement production. The M1903 and its variants remained in service until declared obsolete on July 24, 1947.

U.S. Maxim Automatic Machine Gun, Caliber .30, Model of 1904

The U.S. Maxim Model of 1904 was the first rifle caliber heavy machine gun approved for use as the standard service type by the U.S. Army in 1904. The Army was interested in the Maxim as early as 1887 and procured examples of the “World Standard” Maxim Model 1889 and Model 1900 for evaluation. After sporadic testing, the Chief of Ordnance finally gave approval for adoption in 1904. The first order for 50 guns and tripods were manufactured by Vickers, Sons & Maxim (VSM) in England in the U.S. caliber .30-03.

The Ordnance Department wanted the gun to be made in the United States and enlisted Colt to manufacture the gun. Problems arose and it was several years before Colt could begin production. In the meantime, another forty guns were ordered from VSM. Colt finally began production in 1908. By 1908, the service cartridge had changed from the .30-03 to the .30-06. The ninety guns produced by VSM were all converted to the new service cartridge while all the Colt guns were manufactured in .30-06. Colt produced 197 guns, and with VSM’s 90 guns, total production of the Model of 1904 was 287 guns. Colt never produced any tripods. All the tripods were made by VSM and wheeled carriage mounts were produced by Rock Island Arsenal.

The Model of 1904 saw a brief service life, quickly being declared obsolete by 1915, yet was widely used and saw service in such distant outposts as the Philippines, Hawaii, Mexico, Central and South America. The gun never saw active combat service, particularly in World War I, being relegated to training purposes.

U.S. Automatic Machine Rifle, Caliber .30, Model of 1909

The Automatic Machine Rifle Model of 1909 is commonly referred to in the U.S. as the “Benet-Mercie.” Laurence Benet was an American engineer who worked for the Hotchkiss Company in Paris, France. He, along with another Hotchkiss engineer named Henri Mercie, collaborated to develop an air cooled, gas operated, lightweight machine gun based on the Hotchkiss Model 1900 heavy machine gun design. The Model 1909 differed from heavy machine guns in that it weighed just 30 pounds and was fitted with a wooden stock with elevation gear and a bipod. It was mechanically modified as to how the breech closed and the feedway and feed mechanism were changed. The gun also had a barrel changing ability, unique at that time. The number of parts to the gun were reduced to just twenty five.

The French adopted the French made Hotchkiss gun in 8mm Lebel and the British adopted it in .303. in 1909 and was known on the Continent as the “Hotchkiss Portative.” That same year, the U.S. Army, after lengthy trials, adopted it as service issue as the Automatic Machine Rifle Model of 1909 and ordered 29 guns from Hotchkiss. The Ordnance Department wanted the gun to be made in the U.S. The rights were secured and Colt and the Springfield Armory were contracted to produce the American version in .30-06. Over the next several years, both manufacturers combined produced approximately 670 guns. The Model of 1909 was issued for service with the Model of 1908 Warner & Swasey telescopic musket sight, originally used for sharpshooter use with the Model 1903 Springfield rifle.

The Model of 1909 was issued to U.S. infantry and cavalry troops from 1909 to 1918 and saw limited tactical use in the landing at Vera Cruz in 1913, all along the Mexican border in 1916 and was used in the defense of Columbus, New Mexico against the sneak attack by Poncho Villa in 1916. Though the British and French “Hotchkiss Portative” version was widely used in World War I, the U.S. “Benet-Mercie” was relegated to training use. It was declared obsolete in 1918 and ultimately replaced by the far superior M1918 Browning Automatic Rifle.

Model 1914 Colt Automatic Gun

Invented and designed by John Browning, the Colt Model 1895 Automatic gun was the world’s first practical gas-actuated machine gun. Using a gas-impingement system that operated against a lever that traveled downward and backward in a 170-degree arc underneath the gun, it affectionately became known as “The Potato Digger.” Colt manufactured the gun and was extremely successful in selling the gun world wide in a variety of calibers. The U.S. Navy purchased fifty guns in 1897 in 6mm Lee and another 150 guns in 1898. These guns were used as secondary armament on ships and with naval landing parties and with the U.S. Marines. The gun was also used with some degree of success in the Philippines, the Boxer Rebellion, Mexican border war and the Spanish-American War.

The U.S. Army ordered 100 guns for testing and training in .30-40 Krag. Upon the recommendation of a joint Army-Navy board of 1898 for standardizing arms and ammunition, the Navy rechambered their 6mm Lee to .30-40 Krag, and then they all were changed to .30-03 and ultimately to .30-06. Though the Army, Navy and Marines all used the Colt Model 1895; only the Navy officially adopted the weapon. The Army just continued to buy it commercially as they deemed necessary eventually buying 2,800 guns during World War I. The “Model” designation was a name used by Colt and did not represent acceptance as issue by the Army.

In 1914, Colt modified the Model of 1895 by replacing the heavy, thick permanent barrel with a finned barrel that was easily changeable and became the Model of 1914. It was this version and its variants that ultimately saw use in World War I by a number of Allied nations though relegated as secondary armament and training by the U.S. The gun was used with three types of tripods, basically differing only in height.

U.S. Vickers Machine Gun, Caliber .30, Model of 1915

The U.S. began to realize how vastly under-armed in automatic weapons it was and started a new series of tests in 1913 and field trials in 1914. The new, improved version of the Maxim gun, now called the Vickers, was the clear winner. The new British Vickers was redesigned internally to maximize space within the receiver box by inverting the toggle joint and lock, and the overall weight of the gun was substantially reduced; all without sacrificing reliability. In 1915, the Board of Ordnance unanimously approved the type for the Army as the Model of 1915 chambered for the .30-06 cartridge. They immediately placed an order for 125 guns to be made by Colt and in 1916 placed an additional order for 4,000 even though the first order had not yet even been made. When the U.S. entered World War I in April, 1917, not a single Colt Vickers M1915 had been delivered due to production problems at Colt.

Colt made Vickers guns finally became available in late 1917. By mid 1918, Colt Vickers started to be shipped overseas. The first twelve divisions arriving in France were issued the French Hotchkiss Model of 1914. The next ten divisions that sailed for France in May and June of 1918 were equipped with the Colt Vickers. By August, 1918, thirteen divisions were using the Colt Vickers. In all, 12,125 Vickers Model of 1915 ground guns were produced by Colt.

At the end of World War I, the remaining inventory of Colt Vickers were put into storage and held in reserve. They were ultimately sent to Great Britain under Lend-Lease to help guard against German invasion during World War II, especially after the huge losses of equipment at Dunkirk, while British production fought to rearm the British Army. After World War II, the U.S. did not want the guns returned and the British destroyed the remaining inventory.

U.S. Browning Machine Gun, Caliber .30, Model of 1917

John Browning continued to experiment with different machine gun designs after the introduction of his first machine gun, the Model of 1895 Automatic Gun. He developed a short-recoil, water-cooled gun in 1900 and patented it in 1901. There was no government interest in this prototype and he ceased work on it until 1910 when he made further modifications and improvements to it. Again, there was no governmental interest in the gun.

As the U.S. was being drawn into World War I, the Ordnance Board urgently requested designs for new machine guns. Browning took his heavy water-cooled machine gun along with his new Browning Automatic Rifle to be tested in February, 1917. Both guns tested exceptionally well and the BAR was ordered immediately. As war broke out, another official test occurred in May, 1917. The genius of John Browning shone through with the simplicity of design, reliability and ease of maintenance. Browning’s heavy machine gun was adopted as the Model of 1917 chambered for the .30-06 service cartridge and ordered into production with contracts being awarded to New England Westinghouse, Remington and Colt.

30,089 M1917 Brownings were sent to France before the war ended with 1,168 guns actually being used in the front lines. The first instance of combat usage was in September, 1918 in the battle of the Meuse-Argonne, where, in wet and muddy conditions, the new Browning guns performed exceptionally well with one company firing 10,000 rounds per gun.

The Browning M1917 was to replace the variety of machine guns in American use (British Mk I Vickers, U.S. Vickers Model of 1915 and French Hotchkiss Model of 1914) but the war ended two months later so the Browning actually saw limited use. Yet, Browning’s design was so brilliant that the M1917 and its subsequent variants soldiered on in the U.S. inventory for another fifty years.

U.S. Lewis Machine Gun, Caliber .30, Model of 1917

Colonel Isaac Lewis began development of the Lewis gun in 1910 based upon a previous design by Samuel McClean. Lewis presented his gun for formal testing in 1912 to the Ordnance Board, which included a “stunt” by firing the gun from an airplane – the first time a machine gun had ever been fired from an aircraft. The Ordnance Board took a dim view of the “stunt” and during the rest of the trials took particular efforts to find fault with the gun and rejected it claiming it was no better than the already approved Model of 1909 Benet-Mercie.

Lewis then went to Europe where his gun was warmly received and went into production in 1913 at Armes Automatiques Lewis in Liege, Belgium and at the Birmingham Small Arms (BSA) Company in Birmingham, England. Belgium was soon overrun by Germany in 1914 and production continued at BSA who eventually produced 145, 397 Lewis guns during World War I in the British .303 caliber. The gun was widely used to great effect throughout the war.

Savage Arms Company of Utica, New York began producing Lewis guns for a Canadian contract in .303 and the U.S. Army procured 350 guns (in .303) for use in 1916 along the Mexican border. Nevertheless, the U.S. Army still harbored a grudge against Lewis and his gun that dated back to 1912. The U.S. Navy, however, held no such animosity and purchased 6,000 Lewis guns from Savage for the U.S. Marines chambered in .30-06 and it was designated as the Model of 1917. Upon arriving in France, the 5th Regiment of the Marines attached to the 2nd Division, who had been issued and trained with the Model of 1917, had their Lewis guns taken away and were issued the French Hotchkiss M1914 and Chauchat M1915 machine guns. The American .30-06 Lewis guns were turned over to the Aviation Services. The Army in due course purchased 2,500 M1917 Lewis guns but they relegated them to U.S. training. U.S. Model of 1917 Lewis guns saw little or no infantry combat during the war. After the war, the Army discarded the Lewis gun though the Navy and Marine Corps kept it in their inventory until the 1930s.

Marlin Machine Gun Model of 1917/18

As World War I heated up, orders for the Colt M1914 increased as well. Colt entered into an agreement with Marlin Arms Company on manufacturing the M1914. Marlin’s designer, Carl Swebilius, worked out an improvement to the operating system that changed Browning’s original “Gas Hammer” style lever action to a straight piston arrangement. The Marlin guns, with the exception of a small run of M1917 trainers, were no longer “Diggers,” the piston in tube arrangement ran along the bottom of the barrel and applied the energy to the bolt system.

This change made Browning’s system easier to adapt into aircraft and vehicles; thus, the M1917 and M1918 Marlin Aircraft Machine Gun designations, and the M1917 Marlin Tank Machine Gun designation. Unfortunately, changing to a straight line piston changed the impulse time and energy, and the early guns had trouble in extraction tearing case rims. Adjustments were made to the design, but not before negative publicity occurred. Marlin had taken the position that the ammunition the Army had did not have strong enough cases and the Army said that the Marlin guns had to work with ammunition that was fielded. In the end, the Marlin M1917 type guns were relegated to aircraft use where there was more control on ammunition quality. Some of the Marlin guns had aluminum radiators on the barrels similar to the Lewis M1917, but most had a bare barrel.

The Marlin M1917 and M1918 machine guns did see combat in U.S. use. During World War II, may were shipped to England for their naval defense.

There were an additional 2,816 of the Marlin Model 1917 that are virtually identical to the Model of 1914 “Potato Digger” made by Colt. These were for training in the U.S. Army, and the main difference was in the location of the belt feed opening.

U.S. Rifle Caliber .30, Model of 1917

The U.S M1917 rifle was originally produced as the Pattern 14, .303 caliber “Enfield” for the British. Prior to the U.S. entry into World War I, the British negotiated several contracts with the U.S. firms of Remington, Winchester and Eddystone (a Remington subsidiary), to produce the P14. Collectively, 1.2 million of the Pattern 14 rifles were made from 1916 to 1917.

Upon the United States’ entry into World War I, the U.S. Army faced a service rifle shortage. With the British contracts completed, instead of having the companies retool for the M1903 rifle, the War Department decided to make a few design changes and rechamber the P14 to the U.S. M1906 rimless .30-06 round and the new rifle was ready for production. The U.S. M1917 rifle was officially adopted in April 1917. There were over 2.4 million manufactured from 1917 to 1919 at a cost of $26.00 per weapon.

When World War I ended, the M1917 rifles were prudently placed into storage, after having been rebuilt by various U.S. arsenals. When World War II broke out in Europe, the U.S. and her Allies again faced critical shortages of small arms. The M1917 rifles were pulled from storage and issued to rear echelon soldiers and for training. After the war in October, 1945, the U.S. Army declared the M1917 rifle obsolete. While the U.S. M1917 rifle was more utilitarian then glamorous, it did everything it was intended to do.

U.S. Browning Automatic Rifle, Caliber .30, Model of 1918

As the U.S. was being drawn into the First World War, the Ordnance Board met in May, 1917 to consider for adoption designs for light machine guns and automatic rifles. John Browning had been previously working on a gas-operated, magazine fed, true automatic rifle design and submitted it to the board. It was unanimously accepted by the Ordnance Board and requested that production begin immediately at Colt who had secured the rights. However, Colt was already at peak production and requested approval from the Board for delay in production while they built a new facility in Meriden, Connecticut. Due to the immediate need, the request was denied and the lead manufacturer became the Winchester Company.

The initial contract with Winchester called for 25,000 BARs. They were in full production by June, 1918 delivering 4,000 guns and in July were turning out 9,000 BARs. Colt and Marlin-Rockwell also began production shortly after Winchester got into full production.

By July of 1918, the BAR began to arrive in France and the first unit to receive them was the U.S. Army’s 79th Division and they immediately exchanged their woefully inadequate French M1915 Chauchat machine rifles with the new BAR and began training. In the September 1918 battle of the Meuse-Argonne, the BAR was used extensively. World War I only lasted another two months before ending in November, 1918. Thus, while the BAR was the state-of the-art weapon, it saw limited combat service. Nevertheless, the M1918 BAR was such a fine weapon that it remained as the standard U.S. service automatic rifle after the war and production continued after the war. Of the total 102,125 M1918 BARs produced, Winchester made 47,123, Marlin-Rockwell 39,002 and Colt 16,000.

U.S. Chauchat Automatic Rifle, Caliber .30, Model of 1918

The U.S. was ill-equipped when it entered World War I in 1917 and was particularly lacking in automatic weapons. With less than 1,100 automatic weapons in inventory, consisting of four types in two different calibers, these guns were needed in the U.S. for training the new army. When U.S. divisions arrived in France, they had no automatic weapons.

The French, at war since 1914, had an arms industry in full force. Thus, U.S. troops in eighteen divisions were issued the French Model 1914 Hotchkiss heavy machine gun and the Model 1915 Chauchat automatic rifle: both chambered in 8mm Lebel. The French quickly developed the Chauchat to fill the immediate wartime need of France and consisted of fabricated steel tubing of standard sizes and stampings. The only parts requiring extensive machining were the barrel and bolt. The long-recoil operation, cheap materials, unorthodox enclosed design and hurried production produced a gun that had poor reliability and worse accuracy. But, it was all that was available.

To help alleviate a two-cartridge supply nightmare, the U.S. asked the French manufacturer, C.S.R.G., to produce the gun in .30-06. Good idea, bad execution. The gun was simple in its design and conversion was easy: change the barrel, replace the semicircular magazine with a detachable box magazine, change the angle of the bipod and change the graduations on the rear sight. However, the already poor reliability of the gun went from bad to worse.

The more powerful, straight cased, rimless .30-06 cartridge was very difficult to extract. With its violent action, the M1918 Chauchat tore the cartridges instead of extracting them and the more powerful .30-06 caused major stress on all the working parts causing failures. Additionally, the gun heated up very quickly causing the action to freeze until it had cooled. Due to the enclosed design, clearing stoppages and jams was almost impossible. The gun, in a single word, was awful.

The U.S. nevertheless quickly adopted it as the Chauchat Model of 1918 and bought and paid for 25,000; taking delivery of 19,241. There is no record of M1918s being used in combat and were relegated to training use. They were so bad, that immediately after the war, the U.S. ordered them to be destroyed.

Browning Machine Gun, Caliber .30, M1917A1

In the rush to supply American troops in World War I, deficiencies in design and manufacturing methods of the Model of 1917 manifested itself quickly in operational use. Many of the problems stemmed from the lack of, or improper heat treating of, key internal parts that included the bolt, barrel extension, accelerator, firing pin, trigger and extractor. Inaccurate manufacturing tolerances also contributed to leaking water jackets at the muzzle cap. The most severe problem was due to the pounding of the breech lock on the breech lock cam causing cracks in the receiver side and bottom plates.

As early as 1919, steps were taken to remedy these problems; the most obvious being welding or riveting a “U” stirrup under the bottom plate and extending up each side of the receiver to strengthen the receiver box. A program was initiated by Rock Island Arsenal in 1936 to covert all Model of 1917 guns with upgrades. Changes included a large, new-manufactured reinforced bottom plate that extended up the sides of the receiver and riveted in place, a new belt feed lever, an improved top cover latch that also incorporated a hold open feature and a new rear sight graduated in yards for the M1 ball cartridge (original Model of 1917 sights were in meters). This improved version of the Model of 1917 was designated as the M1917A1. (The “Model of” designation for U.S. arms was dropped in 1939 and replaced with the letter “M”.)

During World War II, more changes occurred to the M1917A1 that included an improved bolt, the bronze end cap and trunnion replaced by steel, the steam tube assembly was strengthened and the rear leaf sight graduated for the now standard M2 ball cartridge. While almost all Model of 1917s were ultimately converted to the A1 specifications, production resumed from 1936 to 1945 with 55,859 M1917A1s being produced by Rock Island Arsenal.

The M1917A1 was used extensively in both theaters of operation during World War II and continued service throughout the Korean War and the beginning stages of Vietnam.

U.S. Browning Automatic Rifle, Caliber .30, Model of 1918A2

During the interwar period, many attempts were made to improve on the M1918 BAR. The M1918A1 and the M1922 were made in very small quantity, with the basic addition of a bipod being the most obvious change. In 1938-39, serious work was begun on what became the Browning Automatic Rifle, Model of 1918A2. The initial experiments with the bipod were expanded upon, and the bipod placement was moved to the front of the barrel utilizing a new flash hider to secure it. The bipod allowed full rotation of the barrel, which made up somewhat for the loss of traverse due to the forward location.

A second addition was that of a pistol grip which extends slightly below the trigger. The method of firing was changed from select fire, (semiautomatic and fully automatic) in the Model of 1918, to dual rate of fire in the Model of 1918A2. This rate reducing mechanism was initially based on the Belgian FN-D BAR trigger group but was later adapted to a US design. Magazine guides were also added to the front of the trigger guard. The fore end was shortened and a heat shield was added, all to help the cooling process. There was a hinged buttplate to add support from the operator’s shoulder, and the new buttstock design allowed for a monopod stock rest.

Production of the M1918A2 was initially performed by upgrading M1918 and M1918A1 BARs. M1918A2 new manufacturing was started in January of 1943. The M1918A2 BAR served in the US military forces throughout World War II, Korea, and well into the Vietnam War. M1918A2s are still seen in various inventories around the world, obsolete though they are.

Browning Machine Gun, Caliber .30, M1919A4

The success of John Browning’s designs is evident in the proliferation of Browning machine guns used by U.S. and other forces around the world. The end of World War I and the advent of more mobile military forces led firearms designers to confront new problems of portability, and the use of tanks and aircraft compounded this. Browning’s basic design for the M1917 series had morphed from water-cooled to air-cooled as early as 1918, and the first models of 1919 Browning machine guns were basically for aircraft use.

The most prolific of the air-cooled Browning machine guns in rifle caliber was the M1919A4. This final variant was designed as either a flexible mount unit for tank use, or for mounting on the M2 tripod with traverse & elevation mechanism and pintle. Production began with the adoption of the M1919A4 in 1935. At that time, all M1919A2 and other earlier variants were started onto a rebuild program to have the longer 24 inch heavy barrel as well as other modifications. By 1939 the elongated slots in the barrel jacket were changed to the quickly recognizable pattern of 5/8 inch diameter holes.

The M1919A4 served well into the Vietnam War for U.S. forces and is still in use today in various armies around the world, primarily in South and Central America and Africa, although most have been replaced with more modern weapons. The M1919A4 was fielded in .30-06, but it has been issued to various armies in 8mm Mauser, 7.62×51 NATO, 7.65 Argentine, and others.

Browning Machine Gun, Caliber .30, M1919A6

The Browning M1919A6 was conceived as a stop-gap measure to fill a void between the M1919A4 and the BAR. The BAR, while relatively light and portable, did not have the capability of sustained firepower. The M1919A4, while perfectly adequate, lacked the ability to be quickly set up and employed and still required the use of a tripod for stability.

The Infantry Board in 1942 investigated many light machine guns of the time, including the German MG42. While a number of designs were submitted, wartime shortages, production constraints and immediate need precluded the design and production of a superior weapon versus modifying a current production weapon to fill the need. (A bird in hand is better than two in the bush.) Reminiscent of Germany’s decision in World War I to develop a light machine gun from an already existing production gun (the MG08/15 from the MG08), the Infantry Board decided to make modifications to the Browning M1919A4 machine gun.

Beginning in 1943, the gun was standardized as the M1919A6 and featured a removable shoulder stock, a lighter barrel with a different barrel bushing to accommodate a bipod and was fitted with a carrying handle. The gun weighed 12.5 pounds lighter than the M1919A4 mounted on its M2 tripod, and was easily transportable and set up by one man. Other than these relatively minor modifications, the gun was mechanically identical to the M1919A4.

Production of the M1919A6 was by the Saginaw Steering Gear Division of General Motors, who produced 43,479 M1919A6s. A number of M1919A4s were also converted to the M1919A6 configuration. The gun saw wide service in the last two years of World War II and continued to see service through the Korean War and the early years of Vietnam.

U.S. Rifle, Caliber .30, M1

Development of the M1 rifle began in 1919. Limited funds and the conflicting ideas of many of those involved caused the program to drag on until 1936, when a suitable prototype finally emerged. Original prototype rifles were chambered for a .276 caliber cartridge. However, the weapons were soon changed over to the existing, standard U.S. 30-06 round by order of General Douglas MacArthur. The decision was due in part to the large stockpiles of the ammunition that remained from the First World War. The basic M1 design was continually refined until 1940 when large-scale production finally began.

The gas operated, semiautomatic M1 rifle was the inspiration of John C. Garand, who designed the weapon while employed by the Springfield Armory. During World War II, the M1 rifle was manufactured by Springfield Armory and the Winchester Repeating Arms Company. Approximately 4,040,802 M1 rifles were manufactured from 1937 to 1945. The remarkable M1 design was to have a service life extending long past the conclusion of World War II.

In 1950, the outbreak of hostilities in Korea brought the World War II M1 out of pending retirement. A dwindling supply of rifles dictated that additional M1s would be needed and production resumed. During the Korean Conflict M1 rifles were manufactured by International Harvester, Harrington & Richardson and the Springfield Armory. During the1950s era, approximately 1,427,970 additional M1 rifles were produced, and many more WWII era rifles refurbished. The last M1 rifle was manufactured in 1957.

Browning Machine Gun, Caliber .30, M2

Immediately following World War I, experiments began on making a high speed air-cooled Browning machine gun variant for aircraft use. The original high speed guns were designed by Colt, and these included the M1918, M1918A1, M1919, and MG40. Each model had its problems, leading to the next variant. Part of the problem was that in going to the newer more powerful M2 .30-06 service cartridge, the cyclic rates went up by percentages in the 20% range. At 1,000 rpm, problem occurrences were magnified.

The final variant of the high speed Browning machine gun is commonly referred to as the “Aircraft Gun” or the “M2”. The prefix “AN” simply stands for “Army-Navy.” There were two basic models of the M2: Fixed or Flexible. The M2 Fixed gun was forward firing only, mounted in the wings or cowling, for remote firing by the pilot on an aircraft. The M2 Flexible gun had a spade grip assembly and was mounted so that an air gunner could engage targets within his traverse area.

The M2 guns were designed so that they could be switched out for feeding from either the right or left sides. This also allowed for the use of a twin mount. Twin M2 Browning machine guns firing at 1,200 rpm each made for a very impressive increase in hit probability in air battles.

The M1941 Johnson Rifle

Designed by Melvin M. Johnson, Jr., the M1941 Johnson was unique for a rifle caliber semiautomatic weapon because it was recoil operated rather than the more commonly used gas operating system. This unique feature made the Johnson rifle easy to manufacture and less prone to gas fouling. The weapon also featured a 10 round rotary magazine that could be topped off with additional rounds. The nomenclature M1941 was a commercial designation as there were no Johnson rifles manufactured under U.S. contracts.

The Johnson Automatics Company subcontracted with the Universal Windings Company to manufacture the weapon at their factory complex located in Cranston, Rhode Island. The company would be known as the Cranston Arms Company. Approximately 30,000 Johnson Rifles were manufactured before production ceased in early 1943.

Although the Marine Corps had chosen the M1 Garand, few M1 rifles were available as wartime demand far exceeded the supply. One feature of the Johnson rifle that the Marines liked was it could be easily broken down. This was considered an asset for their newly formed “Paramarine” battalions where the rifles could be easily carried when disassembled. The Marines procured a limited number of the Johnson rifles for issue to the 1st Parachute Battalion in 1942.

Model of 1941 Johnson Light Machine Gun

Invented and designed by Melvin M. Johnson, Jr., it was his intent that the M1941 Johnson LMG replace the BAR. Despite the light machine gun designation, it really was an automatic rifle like the BAR. Notwithstanding the name game, the M1941 LMG had many unique features. Chambered for the M2 .30-06 cartridge, it had a straight line stock which decreased muzzle rise during full automatic fire; necessitating a high front sight. It was light weight at only about 13 pounds and was very accurate in the semiautomatic mode as it fired from a closed bolt, yet in full automatic mode, fired from an open bolt to assist in cooling and preventing cook-offs from a hot barrel. The magazine well was also unique in that the 20-round box magazine could be topped-off by the addition of single rounds through the right side of the receiver or by five round stripper clips. Additionally, the feed lips were a machined part of the receiver rather than being part of the magazine and thus not subject to deformation. The M1941 LMG also employed a quick change barrel.

The M1941 Johnson light machine gun was never officially adopted by the U.S. but was used by selected units of the Marines and Army. Because BARs were in short supply, the U.S. Marines obtained a small quantity of M1941 LMGs primarily intended for use by airborne units and Marine Raiders which saw combat use in the South Pacific. The Army also acquired some M1941 LMGs for issue to the Army’s First Special Service Force, the OSS and there are unconfirmed reports that they were also used by some Army Rangers.

Though some 10,000 M1941 LMGs were produced by Cranston Arms Company, only a relative few (less than 3 percent) were used by the U.S. with the bulk originally ordered by the Dutch for use in the Dutch East Indies. At the fall of the Dutch East Indies to the Japanese, the remaining guns of the contract were embargoed so as not to fall into Japanese hands and is the reason a number of guns were available to the U.S. as needed.

Browning Machine Gun, Caliber .30, M37

The .30 caliber M37 machine gun was a post World War II machine gun variation designed as a secondary weapon for use on combat vehicles and tanks. The M37 differed from the M1919A4 in that it could be fed from either the right or left side by repositioning of a few parts. The top cover also had a new type latch that could be opened from either side. The M37 was generally used as a fixed tank weapon, but was also utilized in the flexible role, primarily by the U.S. Marine Corps. When used in the flexible role, rear sights were added and the weapon was used on the M2 tripod. Among other improvements, the M37 featured a chromed trunnion block, barrel and booster. Many of the parts of the M37 were redesigned and not readily interchangeable with the M1919A4 machine gun. Rock Island Arsenal and Saco-Lowell Shops manufactured the M37 machine gun from 1953 to 1969. The M37C variation was similar to the M37, but used an electric solenoid to fire the weapon, and rather than manually charged, it used a hydraulic system to perform the task. The M37C was used in early helicopter applications, as well as being fitted in the U.S. M48 and M60 tanks.

With the advent of the industrial revolution in the 1800s, the foot soldier no longer carried just a pike, lance, spear, bow, sword or rifle. The rapid development of more complex mechanical weapons systems necessitated the use of small carts to move materiel right up to the front lines. World War I saw a tremendous increase in the need and use of small carts in all types of applications. Foot soldiers responsible for the newer and larger small arms such as machine guns and mortars needed a mode of transportation that addressed their needs in the field. (See Small Arms Review Vol. 3, No. 10, July 2000 for a discussion of the Model 1917 Machine Gun and Ammunition Carts used in World War I.)

The lessons learned in World War I brought about a series of rapid developments in the inter-war years to meet the demands of a rapidly changing military culture. Among the many items that were further refined were the small hand carts. No longer designed with the horse or mule as the primary means of power the new carts had to be able to withstand the demands of towing by motored vehicles over longer distances and at faster speeds and be more robust in their construction. Of course, provisions still had to be made to accommodate the last line of power: the foot soldier.

Shortly after World War I in the mid 1920s, the Mount, Wheeled, Machine Gun, M1 was developed for the dual purpose which combined the idea of a T base (trail assembly) for the M1917 tripod with that of a two wheeled light weight cart for transportation of the Browning M1917 water cooled machine gun, accessories and ammunition in the set up and ready to fire configuration. The idea being that the set up gun could be quickly brought to use and fired from the cart if need be or the soldier could quickly dismount the gun and tripod and set up in a position without having to assemble the components. A third option was to leave the gun as set up and remove the wheels and simply drop the entire T-frame with the mounted gun on the ground. This method was viewed as especially valuable in sand or soft earth conditions that without it the tripod feet would bore into the ground and the gun become unstable. The M1, the first post World War I hand cart, was a simple T-shaped affair with solid rubber coated wheel rims and a simple bracket to hold extra ammunition boxes.

Quickly on the heels of the development of the Cart, M1 were the Cart, M2 and Cart M2A1. These carts were basically updated versions of the old wooden M1917 Ammunition Carts in that they were still designed to be drawn primarily by horse or mule but were constructed of metal rather than wood. The Cart, M2 was issued for transporting .30 caliber machine gun ammunition, 37-mm gun ammunition, light mortar ammunition and communication equipment. The Cart, M2A1 is the identical cart as the M2 except that it has front and rear brackets specifically for transporting the 81-mm Mortar and Bipod Mount M1.

Next in the litany of hand carts developed in the 1930s were the Carts, Hand, M3 and M3A4 (utility), M4 and M4A1 (.30 caliber machine gun), M5 and M5A1 (.50 caliber machine gun) and the M6 and M6A1 (81-mm mortar). They consist of two types and are of four purposes. The first (earlier) large wheeled type have 4” x 18” motorcycle wheels on a straight axle and are identified by the designations M3, M4, M5 and M6. These carts were classified as limited standard during World War II. The second or small wheel type have 4” x 12” cast aluminum wheels on an offset axle and are identified by the model designation M3A4, M4A1, M5A1 and M6A1. These carts were classified as standard during World War II.

The carts are drawn by man power but are equipped with a lunette for limbering to a Jeep or other small vehicle. When drawn by man power a drawbar is secured to the lunette with the hand cart drawbar retaining pin. When not in use the drawbar is carried on the drawbar bracket which is riveted to the front body. Provision is made for attaching tow ropes with D-handles to the cart body when additional man power is required to pull the load. The carts are also designed so that two loaded carts can be transported on trucks when placed between the seats provided for personnel.

The M3 and M3A4 utility hand carts are comprised of the chassis and body. The chassis of the M3A4 small wheeled cart is composed of an offset axle, tongue and drawbar assembly. The axle is an aluminum-alloy tube and assembled on each end are aluminum-alloy axle brackets that are riveted to the axle. Steel spindles, to which the wheels are mounted on anti-friction bearings, are assembled in the axle brackets and secured by nuts and cotter pins. The axle brackets are fastened to the side and bottom of the cart body by bolts. The tongue is an aluminum-alloy tube reinforced by a liner made of the same material. The spade lunette is riveted to one end and the tongue and axle bracket which fastens the tongue to the axle to the other end. The tongue is secured to the front of the body by a clamp. The body, which is the same for both the large wheeled M3 and small wheeled M3A4 carts, is a rectangular shaped open box which is bolted to the chassis. The M3 body is constructed of aluminum channels and rails reinforced with angles and gusset plates held together by rivets. The M3A4 body is made of steel and does not require the reinforcing angles and gusset plates. Holes are drilled in the body of both the M3 and M3A4 to bolt the brackets which are required to convert this cart for its other uses.

The M4 and the M4A1 .30 caliber machine gun hand carts are converted from the M3 and M3A4 carts respectively by the addition of three brackets to which the legs of the M1917A1 tripod mount are attached. The Browning .30 caliber M1917A1 water cooled machine gun, which is used on this mount, can then be used as an anti-aircraft gun or the gun and mount can be quickly removed to be used as a ground gun. Leather straps are also provided to hold spare ammunition boxes and accessories.

The M5 and M5A1 .50 caliber machine gun hand carts are also converted from M3 and M3A4 carts respectively by the addition of brackets to receive the Browning .50 caliber M2HB, flexible and the M3 tripod mount during transit. Unlike the .30 caliber set up, the .50 caliber is transported in a disassembled state though the brackets are equipped with quick release clasps to facilitate speedy unlocking. A leather strap is provided to secure the ammunition boxes.

The M6 and M6A1 81-mm mortar hand carts are also converted from M3 and M3A4 carts respectively by the addition of brackets and supports to secure the 81-mm mortar M1, and 81-mm mortar mount M1 during transit. Quick release clamps and leather straps are also provided.

Though there are a number of “M” designations for the cart, the basic M3A4 Utility Hand Cart fulfilled a vital need in the war effort by easily being converted to a number of uses merely by the selection of clamps and brackets.

The carts were manufactured in the tens of thousands (some estimates go as high as 70,000) by Rock Island Arsenal, John Wood Manufacturing, Trussbilt Incorporated and Omaha Industries. Yet, only about a hundred or so are accounted for today in conditions ranging from rusted out basket cases to restorable examples. The carts did not have a priority for return after the war and were left wherever they were to pretty much rot away. They were used extensively by the Army and Airborne units in Europe and by the Marines in the Pacific. (As an interesting side note, in the movie “The Longest Day”, John Wayne, playing Col. Benjamin Vandervoort of the U.S. 82nd Airborne Division, breaks his ankle when jumping into France on D-Day and is hauled around on a M6A1 mortar configured cart.)
