Too bad he changed his mind. But Guy is right about the turret shortage of 1942. There is a story about a Russian T-34 that had it's turret damaged and the salvage factory had no spare T-34 turrets. The turrets seem to be more often damaged than the hulls so replacement turrets were always in short supply. But the factory did have several salvaged Pz IV turrets that would fit with an adapter ring. They had to be hand cranked to rotate but the 3 man turret proved to be so much better than the T-34/76 two man turret that it led directly to the development of the T-34/85.
The K&C model shows the Pz. IV/T-34 immediately after conversion and before it was repainted with the German markings replaced by Russian ones. The slogan painted on the schurzen of the actual tank was
возродиться из пепла which is "Reborn From The Ashes"
Here is a photo of a Russian KV-1 with a German 7.5 cm L/43 gun and a German commander's cupola as an example of what the Russians would do.
A common tactic was for a Russian tank unit to approach a German position with captured German tanks leading. The Germans recognizing a "friendly" tank, would delay their fire long enough for the Russian tanks to make a close approach.
The tank depicted by K&C is of an actual tank used by the Russians to lead the attack in Operation Uranus which was the encirclement of the Germans at Stalingrad. It is famous for the assault and capture of the Kalach Bridge by Soviet 26th Tank Corps, which used two captured German tanks and a reconnaissance vehicle to approach it and fire on the defenders getting ready to blow the bridge. It was the only remaining bridge over the Don River and without it, the Russians could not have completed their encirclement of the 6th Armee.
I really hope Andy has time to paint the Russian slogan on the schurzen and replace the German tank commander with a Russian one.
