3 tanks were planned to be designated KV-3, all based on an elongated version of the KV-1/KV-2 chassis. These were objects 221, 222, and 223. This model closely resembles object 223, as it was the only one of the three prototypes actually built. Object 223 is armed with a 107mm cannon, which would have made it one of the most powerful tanks in 1941, if it had actually entered production or combat.
Ordering the small variant will give you a single tank.
Ordering the medium variant will give you two tanks.
Ordering the large variant will give you five tanks.
Too expensive? Want it in a different colour or slightly larger scale? I sell this exact same model
on my website.
