This is a German Tiger I tank used for driver training.
It is HO scale in resin, photo etched bits and resin, I got it from Fidelis Models, my friend Randy always gives me a good deal on kits.
Because driver training did not require combat use, the Germans used the wood gas system to power the tank. It was a system that used wood or coal to run the engine. It was low power fuel and hard on the engine.
This is the PE bits. I don't like PE. It looks great, but it is hard to use and is very fragile. Not what you usually want for wargame models.
