Hello deleighty1,

What you have is a 1/6 scale Stuart tank.I have three of these tanks and there are a lot of other members here on this forum who have these tanks.The bad news is there are very few parts to be had for these tanks.You should start another post specificly asking for "need part for 1/6 stuart tank" and maybe a member here will have what you need.Looking on ebay for a non working parts tank will be your best chance to get a gear box assembly or from a member on the forums.

These are great tanks and there are still a lot of them around,but the problem is getting replacement stock parts for them.Hang in there and I think someone here may be able to help you out.
