The Aussies have their own way of doing things and Army Private Evelyn Ernest Owen’s clever improvement over the cheap and crude but mostly serviceable STEN submachine gun is definitely a case in point.

In order to encourage SAR’s readers to do further research, what’s presented here is a selection of archive photos depicting a few highlights of the simple, reliable and effective Owen Machine Carbine’s distinguished service with Australian forces from 1942 into the 1960s.

The Owen was developed and manufactured in Australia and is distributed throughout Southeast Asia. It is unusual in that it has a quick-detachable barrel. The Owen can be found with several different types of buttstocks. This submachine gun is recognized by its top-mounted magazine, prominent barrel lock, and compensator on the muzzle.
