Actually it's not a tamiya. It's a tamiya knock off from the late 80's early 90's. There were a number of them back then. The world engines road runner and rock buster were the most common. They were actually pretty well built and rather rare. A couple of others were cyclone and cyclone 2.

From what's left of body it appears you have a rock bUster.
