Soviet 45mm AT Gun model 1937 WALKAROUND
The 45 mm anti-tank gun model 1937 (factory designation 53-K) was a light quick-firing anti-tank gun used in the first stage of the German-Soviet War. It was created by Soviet artillery designer M.N. Loginov. Due to insufficient armor penetration it was replaced in service by the long-barreled 45 mm anti-tank gun M1942 (M-42).
