Help with propeller ID

[Csam]

Hello-
I just bought it off ebay. The only markings says 72 x 44.... no model number or decals. It consists of 4 pieces of laminated wood. See attachment. Any ideas?

It looks like an ultralight prop to me and that's one way they are usually stamped. The numbers describe length and pitch in inches. Looks like nice workmanship with contrasting wood, but it's not made for a certificated aircraft.
