Manufactured by Zastava Arms for the Yugoslav People’s Army. 7,62x25mm Tokarev 71-round removable drum magazine, open bolt blowback select fire, sexy heat shield. Despite the external resemblance and interchangeable magazines, this gun is more similar to the excellent Beretta M/38 than the Soviet PPSh-41.
Manufactured in Long Branch, Toronto, Canada c.1944 - serial number 1?L6733. 9x19mm Parabellum 32-round detachable box magazine, blowback open-bolt semi-automatic, removable skeleton stock. I love these khaki cloth magazine pouches. Bonus round, a STEN MkIIS fitted with a pistol grip :
