It’s a cable winch handle. I’ve had a couple of these square shaft winches and have seen them sell at swap meets and are almost always missing the handles. The winches are usually mounted on trailers and the handle gets left on the square shaft and falls off during hauling.
Desertexplorer,
I just want to say thank you for your response on this. For some reason I never saw the reply until today when I searched some of my old posts.
So THANK YOU very much for letting me know what I have. I really appreciate your help. PM me if it is something you need.
