Let's start with the obvious: This is a mid-production unit judging from the lack of pistol port and the dished rubber road wheels. Zimmert is wrong. It is applied only as high as someone on the ground could reach normally so coating the turret is wrong. Second, by the time of the Ardennes Offensive Zimmert was no longer being used on tanks and stopped being issued to units.
If this tank is an older vehicle why is the coating in such good shape? It can't be a factory job as by this time the late model production Tigers with resiliant steel road wheels are in production.
The markings are totally bogus. The large tiger? Show me a picture of that! Aside from that, there are few crews that would apply such a nice and temporary whitewash finish to their tank.

Less obvious: The shovel on the front. Nice wood handle and very clean....and too large...
Where is the tool box on the left rear of the tank?
Tow cables one side only and no track changing or repair cables?! Rrriiiggggttthhh....


For $150 I'd expect perfection. That isn't. It's a heavy dose of artistic licsense and little more.
