This (KV2) has been been on my Barbarossa 1941 (1/200 scale) wish list for a long time. It is the eternal frightening tank (along with its sister KV1) that the Germans encountered in 1941 and was looked upon with a sense of awe and arcane wonder. It was usually photographed with a German Landser looking at or standing on a knocked out or abandoned example (see below, stage one "flash removal"):
It almost looks like a sensible tank in 1/200 - its insanity shows up more in 1/76. I remember I needed two of these for one of the Spearhead Scenarios. It was a "bunker buster" (a child of the 1940 Finnish War requirements for getting through the Mannerheim Line) rather than a true MBT, but it looked like a prehistoric monster.
Note: That closes off my 1/200 - 1941 Russian Tank wish list, but for 1942-43 opens up my need for T60, T70 and lease lend vehicles (M3 Stuart, Valentine, Matilda, M3 Lee, Churchill, Tetrarch - methinks I would need battalion batches of ten for each of these, apart from a singleton for the Tetrarch).
