  • Please help! I need to identify this prop.

    Hello I am new to this site and I need some help figuring out what type of prop this is. It has no markings on it. It is roughly 7-1/2 feet long and 8 inches wide at the thickest point of the blade. Any insite would be great. Thanks. I have been to the suggested websites and found nothing the same as mine so I am trying here.

    It's going to be hard to identify it without any kind of markings on it. Have they been sanded off or does it look as if it was never stamped?

    It's possible that it is WW1 vintage, although the length is a little small for that. Check the hub dimensions and see if you can match it to a specific engine. The hub is the so called "integral" spinner design, and it appears to have been carved out for a clock at some point, but you can still measure the bolt hole diameter and the center bore diameter from the back, where it's still intact.

      It has the look of a 1920's or 1930's British military propeller. If the shaped hub is made of thin plywood, this will be confirmed.

      If it is made of solid wood then it might be for a 1930's small commercial aircraft. The size is about a foot larger than most of the DH Moth aircraft. Eitherway, the prop has the look of a Watts designed prop made by the Airscrew Company. The Hawker Tomtit fighter has a Watts prop of 7' 9" in diameter.

      Is there any sign of a small brass plate having been attached to the base of the prop blades? if so this might indicate the site of a Watts data plate.

      With regards,
