I don't think I've ever seen a present day clip of a KV-1 running. No idea where this one is but it looks really good:
Old Sherman hull in background of scrap yard. Nice renovation but the tank in service I believe was not so successful. Regards Tom
Seeing what one really looks like 'in the wild' suggests a late war design to me. Hard to believe this brute was on the battlefield in 1939 against the Finns. Must have yielded a lot of 'uh oh' thoughts from Panzer III and IV crewmen.
