Vintage Model Airplane Engines & Props1950s era engines and props.Two engines with props. One engine mounted on wood. Two propellers.These came from my late grandfather's collection. Sold as-is. I don't know anything about the engines. What you see is what you get.Props are 10" made of wood. On prop is labelled as "SUPR-SCRU." The other prop says "45C" as well as some additional text that I'm having trouble reading.Apparently, based on labels accompanying the engines, one of the engines is and O.K. Cub - .049 CID from 1957 while another is and O.K. Cub - .074 CID from 1956.
