Australian Austen Mk I 9 mm sub-machine gun, 1942 (c)

The gun is equipped with bakelite grips and is camouflaged with green paint. In 1941 Australia possessed no home manufactured sub-machine gun although the Owen SMG was in the initial stages of production. The Australians therefore produced a modified Sten with a mainspring, bolt and folding butt derived from the German MP40 weapon, the Austen (Australian Sten).

Donated by the Royal Army Ordnance Corps
