Can you help me identify this propeller. From the numbers on it, I'm thinking it is from the early 1940's. It is about 40 inches long and it squeezes onto a 2 inch shaft. It seems to be made of fabric. From a distance it looks like wood, but up close you can see it is fabric. Any information or direction to look would be helpful. I am totally stumped.

Sorry I have no idea. My guess is that it is NOT from an aircraft, but possibly a small drone, or a fan. Hartzell Fan had a material that they called "Hartzite" from the early 40's for cooling tower fans, later used by Hartzell Propeller for propeller blades.
 
I agree. The no. P1240 looks like the Hartzell prop. Here the similar 35 1/2" ones of the manufacturer - no.P1185 and P1186. IIRC, during the WW2 the company produced metal propellers for Hamilton-Standard. After the war, Hartzell started producing the first composite propellers. The P1240 just looks like the composite prop. So it is a post war one IMHO. All these showed below are the metal props.
