F-22 Soviet 76mm field gun/ German Pak.36(r)

F-22 76mm gun model 1936 was Soviet 76,2mm divisional semi-universal gun which combined capabilities of a divisional gun and anti-aircraft gun, adopted for the red army service in 1936. In 1941-42 Wehrmacht captured hundreds of the F-22s. Initially they were adopted as field guns, designated FK 296r, but late 1941 it was decided to rebuild the gun as an anti-tank weapon, 76,2mm PaK 36r. 560 pieces were converted; some of them were used to arm Marder II and Marder III tank destroyers.
