Thank you for viewing! This is the first Tamiya M4 Sherman, believed to have been released in 1974, which is now difficult to find! I haven't seen any for sale on Mercari, so I think it's quite rare. The M4 Sherman series was the first radio-controlled car released by Tamiya, and it's super rare! Regarding the condition, the motor gear on the right side of the chassis (when viewed from the rear) isn't working properly. I don't know if it's because there's no grease or if the gear is damaged. The left side works fine. There may be other missing or broken parts. Please consider the above points before purchasing! Traxxas Associated Losi Axial Maxx UDR
