The tanks in the photo are the version modelled by Trumpeter as the KV Small Turret, though they should strictly speaking be designated KV-1 (Small Turret KVs had the pointed mantlet)
Trumpeter KV Note the tanks in the photo have applique armour on the hull sides and front and have AA MG mountings on the commander's hatch. It's possible that Kolobanov's tank could have been a KV-1E as they are evident in photos from the early part of the German invasion.
