Trying to identify this prop I got in a box of parts. It is a 2 blade, pin drive has no markings on it. Turns out it looks like a lot of props. Thought I had it identified as a 40-47 merc 6 Hp. It also looks like the a 7 1/2 Elgin, Firestone W. Bend prop. Would like to identify it and see it put back on someones project motor. (looks like Michigan G- 50 or K-15) Thanks in advance
