Testors and Cox Surface Vehicle Parts

I am still going through stuff since I retired and thinning things out. Thanks to those who purchased stuff from me in the past!! What i have now is some loose parts. I'll describe them as best I can;

1) First is some sort of Testors vehicle engine/tank mount with engine, plug and heat sink. I have not the slightest idea what it's from. i don't remember if I have listed it before. Check out the pictures and ask if you need more. 720 plus actual shipping. i use Pirateship.com for shipping rates.

2) This is a Cox pull start mechanism parts. I am not sure if it's complete or not. it looks like the parts I have seen on the Dune Bugger and Baja Bug, maybe even the Chopper Trike. Asking $10 plus actual shipping cost. Check out photo and ask for more if needed.
