Wz. 35 anti-tank rifle

The karabin przeciwpancerny wz. 35, a Polish 7.92mm anti-tank rifle abbreviated kb ppanc wz. 35, was used by the Polish Armed Forces during the 1939 Polish campaign of the Second World War and later by several Axis armies, designated for its 1935 design year. Also known by the codename Uruguay and by the name of its designer, Jozef Maroszek, it was a top-secret bolt-action project of the Polish Army fed from a four-round box magazine, kept hidden enough that neither German nor Soviet intelligence was aware of it before the war.
