T-34-85 and T-34-76 in the East German Nationale Volksarmee. The T-34-76 has a small turret and lacks railings for infantry, meaning it was likely produced in early 1942.
The above image is dated somewhere around the late 1950s to late 1960s, but here is a much more recent image of two T-34-76es in North Korean service, a model 1941 and a model 1942.
Despite the poor picture quality, the suspension is obviously different. The road wheels have been replaced with post-war ones, and the track is from a T-55. The gun, however, is still the same F-34. I wonder if they developed any improved ammunition for it.
Edit: Another T-34-76 from North Korea. This photo is dated 2013.
