  • 12'4" wooden prop

    Suspended on ceiling and unable to see any stamps, nos, ect on reverse side.
    Uncut with blades covered with a protective black linen type material.
    Maybe unused and originally thought to be a Watts make.
    Too long for Spit/Hurri/Fury and has low speed tips.
    Poss. seaplane but...…….any body go any further ?

    There's not too much to go on. At that size it might be for an airship of some kind, and note that it's a left hand thread, which can indicate a pusher configuration.

      Hello Synergy!

      Your prop is British and probably dates from late WW1 or the 1920's. Can you tell us how long it is? I might then be able to identify it. It has none of the characteristics of a Watts prop, nor is it from a seaplane. It is probably covered in Irish Linen painted black, which is characteristic of RAF props from 1918 until circa the mid 1930s when a Hydulignum finish came into use. This was a process devised in Germany in the 1930s and made under licence in GB. It is described elsewhere on this forum. The process used many thin laminations glued together, a process today called laminates, and the laminates were put into a sheath before the whole prop was immersed in liquid resin at a high temperature.

      With kind regards,

      Bob

        In the thread title it’s 12 feet, 4 inches. Note the 10 bolt hole hub and the left hand thread.

            Wrong rotation for a Merlin, and the Spit/Hurricane used a 12 bolt Watts hub.

                    I wouldn't really know, but everything has a value to a collector. There won't be many surviving, but there probably isn't any demand either. I am not aware of any museum examples of the Shark.

                    However it is a Watts propeller, designed by the great British airscrew designer Dr HC Watts.
