Help with ID

Hello. We have a 48 in wooden propeller with no markings on it. It has one bolt hole in the center. I am attaching two photos. Thank you in advance for any identification help you can offer!

It's almost certainly NOT a propeller made for a certificated aircraft. It's shorter than 99% (or more) of the propellers used on common aircraft, and is half the size of the typical propeller used in the teens or earlier, when engines turned at very slow RPMs.

I'm guessing that it was a replica project of some sort, and looks to be nicely done in that regard.

Thank you!
