I was going through some of the pictures that I have taken in the past and found these. This sub machine gun was made by S.A.M.T. of Rome. It is reported to have been design by Toni and Zorzoli Giandoso in 1944. Never being produced in quantity, approximately 6000 were made, it is none the less an interesting combination of Sten, M-3 grease gun and Beretta.
You can see the grip safety that was used on the magazine housing.
The tooling was sold at the end of the war to Burma and made there.
