  • Wooden Propeller

    I have an old Wooden Propellor that I would like to find out more about and possibly the value:

    The diameter of the propeller is 78 inches.

    numbers on the prop - A2511 DFS 78F1-60

    There are 4 Bolt Holes

    The bore hole is 3 ¼ “

    The bolt holes are 5 ¼” center to center.

    The size bolt holes is 3/8"

    Decal is Flottorp - Grand Rapids MI

    The 4 bolt holes are unusual, but the size and pitch are certainly consistent with a certificated aircraft. I know that there was a Kinner engine hub used on an Interstate L4 that had a 4 hole hub, but I have no idea if yours was used on that or not.
