Which was the simplified version of the Lanchester which was masses produced after the lost in France the than they kept on simplifying it it till they made the sten mk2 which many where made

A model of sten that was made near the end of the war in 1944 many sten MKV’s where made in the beginning production they gave it a pistol grip in the front till they kept on breaking when they stopped making them and around the same time they made it suppressed
