Comments: This early Buffairo Propeller was designed for use with either the Curtiss F Boat, the model 40, and the model MF boats, all using a 100 HP OXX 3-6 engine in a pusher configuration. The drawing number (11386) is listed as a Curtiss Propeller (CP) blueprint but was likely manufactured under agreement by the Buffalo Aeroplane Company. Little is known of this manufacturer, but this propeller had become obsolete by 1920 and was auctioned off as surplus.
