Default Help identify vintage airplane propeller

I cant seem to find anyone who would be able to identify a very old propeller in good condition that i found in my grand fathers barn, i dont know much at all about it except that it is a 100 H.P. Curtis-Lang and it is 8 ft. 3 in. in lengh with brass tips, 8 bolt pattern, lots of egraved markings on hub area,and seems to date about 1920-25. Can anyone help? I've had trouble trying to post pictures of it on this site, if anyone would like to view them i can give you my personal email and they can be viewed. Thanks all, Falcon.

I could not find the drawing number (80 in any of my limited references, and it might be hard to identify any other way. It's a little unusual in that it is a left hand prop. Did you check the hub dimensions? You might be able to narrow it down to a specific engine, which would be a start.


See http://www.woodenpropeller.com/Hubmeasure.html for instructions and link to dimension chart.

The only Curtis engined prop with a diameter of 2500mm that I know of is from the 90hp OX engine which powered the JN3 and the Maurice Farman This had a drg no of AD587.
