Nine bolt holes is unusual, but without numbers it will be hard to identify it. It also looks as if it may have been cut down from a full sized propeller with damage on the tips, which is not an uncommon practice.

When I was young I heard say that it was a propeller used on the small Nieuport airplanes but I have no evidence for this.
About the possibility that it might have been cut down, of course I cannot exclude it, however there is something that in my view speaks against it: at the point where the curvature changes on the leading edge there is one peg as if to reinforce the bonding of the first layer of wood to the second one. The peg goes fully through and there is one on each blade. I wonder if on would have seen any utility to drill holes and place these pegs after having cut down the blades if the the propeller was only further destined for display.

[Dave]

The pegs may have been in place before it was cut down. It's really too small to be used on one of the typical Nieuport engines, and its shape is just not very typical of anything commonly used on aircraft.
