Wondering what aircraft and age of this propeller...
Thanks in advance for any assistance.

Would you please give us the diameter and other dimensions and perhaps post a picture? I'm thinking this may be a test club used for testing aircraft engines.

thanks!

Thanks, I already got the info from Dave. It is a test prop... 66".
Thanks again!
