From Wikipedia, the free encyclopedia
The 3,7 cm KPÚV vz. 34 (Czech: kanón proti útočné vozbě) (designated 3,7 cm PaK 34(t) in German service) was an anti-tank gun produced by the Škoda Works in Czechoslovakia. Škoda's own designation for it was A3. It is not known if guns seized by Germany after the occupation of Bohemia-Moravia saw service in World War II. Slovakia acquired 113 when it declared independence from Czechoslovakia in March 1939.[3]
