    The carved hub wouldn't last a minute under power.

    Hi Kris,

    It looks like it may be a prop for an aircraft/airship mounted wind generator. This generator below is from 1918, it was used in WWI aircraft to provide power for the primitive radios used for artillery spotting. I am not the albino.

    Regards, Ned.

    Ok. So if like Ned says it drives something like a generator then it would be strong enough but not if it was being driven by a motor IMO. The blade root / hub looks just too weak

    I was also thinking it could or would generated power to something and not to impel.

    I agree with Dan on this one. The hub is too small, made of multiple sections and IMO to thin to handle bolts being driven through to mount to the shaft. There are also pins that appear to be in the hub that would get in the way of mounting bolts.

    Just my opinion.

    The blade has a very flat angle/pitch that whilst giving sustained power to a generator over varying speeds, is not giving any thrust or torque worth worrying about that may cause it to fail if it was under adjustable mechanical power from an engine. All that's required is for it to turn the armature of the jenny at a speed sufficient to produce the electrical power needed to run the radio and hence it doesn't need to be as robust or efficient over a range of cruising speeds......I think.

    Regards, Ned.

    Maybe there was a clock or something else mounted in this propeller and was it just a decoration piece like this:

    Thanks for the input guy's!
    I was redirected to a propeller forum (yes it exist!!;-)).
    The only answer I got there, so far,is ;
    At best, it was an early auxiliary prop of some kind. The hub has obviously been cut out for a clock. Positive ID is probably impossible.
    I think I 'll stick to that!
    It's dimmensions makes it very good to be used in a small aviation display I might put up in a while.
