Default 12-foot propeller identification

I have a propeller that is 12 feet long, tip-to-tip. I can't find any identification on it, other than the numbers "4015" stamped on one blade. There appear to be no markings on the hub, which is 10 inches in diameter and has eight bolt holes.

I live in an agricultural area so it is likely that this propeller most recently came off a ca. 1950s wind machine. I'm pretty sure that it's an airplane prop, though, and not a dedicated wind machine prop.

Any insight you could provide would be appreciated. Thanks!
