That AA gun could be the Soviet Bofors copy, specifically the 37mm M1939 (Soviet name 61-K)
Apparently the Soviet navy got some Bofors guns in the 1930s and developed a 45mm copy but the army wanted a 37mm version. This was the 61-K.
Also made in Poland and China. Yugoslavia was a customer for the 61-K along with Romania and East Germany.
