This model is a hybrid of two german super heavy tanks projects: Maus and E100 Alligator.
From Maus it has a main carcass and turret is from E-100 Alligator.
This model is not pretend for 100 percent historical realities. Most of detailes (such like a tank tread and tracks) were taken from other tanks and my fantasy
model consists of five parts: 1. Carcass

Verts:3485 Faces:3326 Edges:6710 Tris:6271
3. Tracks

5. Right tank tread

Total: Verts:54735 Faces:53691 Edges:107303 Tris:102215
The model does not include texture units, but there are unwrapped UVs.
Blend file also includes curvers of tank tread, so it can be easily change.
