“… when encountering difficulties on the heavily fortified Mannerheim line during the Winter War in Finland, the General Staff demanded a specially equipped version fitted with a heavy howitzer, intended to deal with concrete bunkers, in support of the regular KV-1 units. Instead of choosing the more pragmatic solution of a traditional SPG, they decided to use the same turret ring to accommodate a fully traversed, redesigned turret that housed the gargantuan howitzer. This gave the KV-2 an unmistakable profile, with its towering turret … Only 203 were built in all from late 1939 to mid-1941.”

I had started a KV-2 build previously but had to abandon it due to painting problems. In real life it seems to have been an unsuccessful vehicle, but will no doubt be a presence amongst models of the same scale. So, this is my second attempt.
