I'll look in the junk pile for you and see if it's still there and hasn't made it to the scrap yard.
I have/had(not sure yet) an old, old, 'rebel' trolling motor that was pretty well intact, just didn't work anymore. You can have it for the cost of shipping if it will help.
I also have/had a mount built to hold a transom mount trolling motor. You removed the factory mount and mounted this to it so you could pull it up and down like a foot control motor. I believe it also had an extension handle on it.
I'll dig around today or tomorrow and see what I can find.
