I have a McCauley B2D34C211 that is 80 1/4 inches long. It is for a 180hp Lycoming. It is zero time since a o/h. Logs are lost. It has wide blades like a C224. I bought it for a get me home prop. Price is $1,500. It might work for other Lycoming engines experimental etc. If you want paper work it would be $1,000 from a prop shop to inspect it. I can send photos via email or smart phone.
