BRAND NEW, NEVER USED OR INSTALLED. I'm sure this will fit other Tamiya vehicles also. Although I'm not sure which ones. This was the original Tamiya 22T 0.6 Module (06 Module) Aluminum Pinion Gear from one of my Tamiya kits. I ended up building the kit but used at 24T pinion Gear, instead. This was never used. So it has been just a spare part sitting around for a while. I thought I'd see if anyone could use this pinion gear.
