I have what I'm told is a propeller for a Thomas-Morse S-4C. There is damage to the front of the center hole. Someone notched it into a square to inlay a clock, I was told. Other then that, its in stellar condition. I'll get some photos out around July 4th, when I'm back. It's been sitting in my garage collecting dust for 20+ years. If anyone is interesting in telling me if its worth anything, and, or wants to buy it, email me. I'm located in Southern California.
