    Hi, I guess this is a usual question, but having owned my lovely propeller for many years not knowing when it was made etc. I have decided it is time to try and discover its origins.

    I checked the list, kindly provided here and although close I could not actually find an exact reference.

    Numbers etc are:
    Y524
    G1678N32
    250 HP Puma
    Dia 8-6
    Pitch 8-0

    It is constructed of laminated hardwood of some description and has brass bound tips which have screws or rivets soldered in place.

    Any help would be greatly appreciated.
    Regards
    Alan

    I have moved this to the "Early" Wooden Propellers category because I believe it is most likely a WW1 era prop. The "Y" prefix typically indicates a design by A.V. Roe Company. However, although there are suffixes both preceding and following the number 524, I don't see that specific model list in Bob Gardner's book or in other references. I think the "Puma" refers to a Siddeley Puma engine developed late in WW1, but I don't see any references to AVRO aircraft using that specific engine.

    Bob Gardner may be able to more accurately determine a manufacturing date based on the production numbers, G1678 N32. With a relatively high G number, it probably was produced after the end of WW1, but I don't have an accurate time frame if it was.

      Alan,

      I don't have that drg no in my database either but Googling 'Avro' and 'Puma engine of 250hp' produces the Avro Manchester a twin engine bomber prototype that first flew in 1919.

      The batch number, G1678, is also from that sort of time.

      With kind regards,

      Bob

        Thank you both for such prompt replies to my enquiry. I shall now have to look up the plane and engine concerned, at least that gives me a starting oint.
