Haha, yes this is interesting to say the least Haw-Haw :P I think everyone is correct here.. I have a mix of old and new parts for this tank. I'm glad I have what seems to be the new turret, as mine does not what is pictured in your photo at all, and that seems to be one of the major weaknesses.
A little miffed that I didn't get new roadwheels but it won't matter, ordered a set of the new metal wheels w/ bearings from TankArmy and they hopefully will be nice.
I'll put together a build thread eventually
