Can anybody tell me anything about this prop? Like what it came off of??

The hub has 8 mounting holes and is stamped with 3293. On one side, you can kinda see in the picture it says:18' x 5' 3"RHCP 42548. The other side has:2H - SSE 580 - 174. The emblem says: Buffalo Aeroplane CorporationBuffalo (encircled)Air Screws Bonitas Prima Buffalo, NY USA

The prop is pre-1925. That's about all I can help with.

Looking at the markings they seem to me to be 8'x5'3". So is it 8 feet or 5 foot 3 inches long? RH probably implies right hand turning. Other numbers could be model and serial numbers. Any word on Buffalo Aeroplane Co.? What about the ears sticking out at right angles to the blades? Are they attached to the hub? Metal or Wood?

Looks like it says BUFFAIRO, not BUFFALO.

The usage of this large, wide bladed propeller is unknown, but the hub dimensions are consistent with an OX5 sized hub. It is likely that it was used on some form of flying boat in the late teens. Little is known about the Buffalo Aeroplane Corporation, but another propeller manufactured by them can be found here. This propeller is in good original condition with good decals, although they are dark in subdued lighting conditions.

Comments: Built by the Buffalo Aeroplane Corporation (Buffairo), this propeller was sold as surplus by the Navy in 1920. It was used on the Curtiss model F flying boat, designed in 1913 to 1914 and ordered by the Navy around 1916. Using an OXX-3 engine necessitates the Left Hand rotation to make it a pusher prop.


Not sure that is the exact prop you have, but at least something related.

So that explains the dimensions - 8 foot length and a pitch of 5 foot three inches.

Interesting prop.
