Cox BRONCO Bicycle Engine

Newbie to this site, just joining today however I do have well over 1700 POSITIVE Feedbacks on eBay.

I have two (2) Cox BRONCO bicycle engines. One would be complete, the second very near complete. That means Twist Grip (throttle) assembly, the special handbrake lever that lifts and locks the engine up off the tire, cables, mounting hardware etc-things like that. Both with excellent compression, just never got around to mounting one on a bike!
Almost positive I have at least one original Manual but if not an original, then a scan, for sure.
I get the paperwork mixed up as I have both the BRONCO engine, BEAVER (chainsaw) engine along with a general service Series 140 Engine thats on a factory engine mount.
Bonus is that I also have the MSO (Manufacturers Statement of Origin) from Cox so a title could be secured-back then anyway! It's never been filled out and guaranteed original.
I'd consider selling them for a realistic $$ offer. And realistic means more than the $200. another person had posted...
If I seperate the two, the one thats incomplete (the engine itself is absolutely complete!) would have to go first.
I need to dig these out and figure out how to post pictures, I guess!
Shipping would be from Illinois.
Thanks for looking !

Where at in Illinois? How much for the not as complete engine did you have in mind?
