"Kommando SMG", .9x19mm-Parabellum, 550 RPM, 30-rounds magazines. Made by KOMMANDO ARMS MANUFACTURING CORPORATION of South Africa, it is essentially an advanced version of their "Sanna-77" weapon, built in both selective-fire SMG and semiautomatic police carbine versions between the end of the '60s and the beginning of the '80s by DAM PIENAAR ENTERPRISES: the SANNA-77 was a South-African copy of the czechoslovakian CZ Sa25. Both DAM PIENAAR and KOMMANDO ARMS are defunct, now. It was manufactured in very limited numbers to participate a trial of anti-terrorism guns, it was not adopted, most of them went as parts kits in the USA, the gun as you see in this picture was smuggled in the UK and confiscated by the Customs.
