  • 4 Blade Prop

    Saw this on everybody’s favourite online auction site.
    At first I thought it was a test club but after further inspection I think it is a cut down propeller.

    It hasn’t had a bolt circle drilled and is stamped “DRG T2950”.

    Any thoughts?

    You could be right.
    My Fiat coupe 20vt had Borletti clocks though.

      Looks like an RAF target tug, winch generator propeller.

      There are a few posts about them:

        I do believe you are right. I hadn’t appreciated the scale from the photos.

        Interestingly, one of the threads that you linked to mentions T29506 as being the drawing number for a target tug application. On closer inspection, I think this one has an extra digit which I can’t decipher, although I don’t think it is a 6.
        Seems reasonable, though, that a drawing number in the T2950x series would also be for a target tug winch.

        Mystery solved; thank you!

          I think test clubs have a constant pitch angle from the hub to the tip vs. the changing angle all along the blade of a propeller designed for propulsion or power generation.
