Cheetah patents?

For those of y'all blessed to have one, please post any patent numbers that you can find on your Cheetah! I am guessing that at least the chain drive was patented. Those wanting to attempt building a remake could use the patent information as a guide.

Thanks!

Cheetah photographs!

I've added 4 great photographs sent by johnnymonstrous. Thanks johnnymonstrous and other folks who have sent in photographs!
