This is a Mark I Owen Gun from 1942. It was known officially as the Owen Machine Carbine, an Australian submachine gun designed by Evelyn Owen in 1939. The Owen was the only Australian-designed and main service submachine gun of World War II, and it was used by the Australian Army from 1943 until the mid-1960s. Its salient feature was a rather odd upward alignment of the magazine, requiring lateral displacement of the sights.
