Great work! I would love to see more different versions of this tank (and other WWII tanks). This seems to be the B-Version, but the main gun is quite a bit too long for a 7,5-cm-KwK 37 L/24 (?)
There were many bizarre tanks like this out there in the first and even in the second World War. For example, the mine exploder T-10 in WWII (also a remote-controlled tank-prototype) was a tricycle on an M4 Sherman chassis
Great job!
