I have been collecting bits for it for some time, this one came from a US Army firing range and it is one of two we were lucky enough to acquire, it came with a good set of steel tracks and a turret. It is am M4A3 and has the remains of a badly shot up GAA engine still in the engine bay. What we did not get was any gun parts, barrel or mantlet. so as always if anyone can lend a hand tracking down any parts it would be greatly appreciated. I hope to call on Adrian B's crazy fab skills for tanks and turret basket when the time comes! I will post pictures of the M4A3E2 Jumbo we also purchased from the same collector, who would probably not want me posting his name on here for privacy sake.
This is M4A3E2 Assault tank #77 or "Jumbo" as it has become affectionately known. One of only 250 or so ever produced.
