Default Stone Propeller Chicago - found in my garage possibly an unairworthy one


I found what I think is a stone propeller from the 1940's. I think it might be one of the ones that were made to not be airworthy, on the back by the hub it is stamped letters THY. Assuming this may be part of the not airworthy designation.

I'd like to find out and details about this propeller and also what it might be worth if I sell it

Any input would be most appreciated
