  • Identifying WWI prop

    Hello,

    Thanks for setting up this forum! My dad just passed down his WWI propeller to me that he bought from antique shop in London 30 years ago. He was told at the time it came from an Avro that flew in WWI.

    Any help in identifying what aircraft it came from would be appreciated.

    The markings on the prop are:

    DRG P23
    D 8-5' P 6-10
    TR_CTOR( I couldn't identify the 3rd letter)

    110 CIERGHT RH(not positive on the IE)
    1579( not positive on the 9)

    The final markings include four small boxes right next to each other with the same markings- they are:

    A.I.D.
    357

    See pictures posted as well.

    Thanks in advance!

    Best,

    Andrew

            The drawing number, P23 is listed for use on a Nieuport, although it doesn't specify the model. Other markings indicate a Clerget 110 HP engine, Right hand tractor application, and diameter and pitch.

            The AID is an inspection stamp from the Aeronautical Inspection Department

              Hi,
              The shape is strangely like Régy French props!
              Could you post clear close-ups of the two "flat" sides of the hub?
              And give the exact length of the prop?
              Regards,

                I noticed that as well. It looks very similar in design to this Regy
                prop
                .

                  Thanks for the quick feedback!

                  I just measured the prop and it measured 8 feet 5 inches. Which makes since with the marking

                  D 8-5'

                  Additionally, it appears there's an additional number on the prop but it's quite faded. I believe it's 13. It appears above the name of the 110 CIERGHET RH line.

                  Also, attached is a more detailed photo of the flat portion of the hub.

                      After doing a little follow up research it appears that the Nieuport 16 and Nieuport 17 were both powered by a 110 HP LeRhone engine.

                      I couldn't find any caudron aircraft powered by a 110 hp engine.

                      Any chance it came off of an AVRO aircraft like my dad was originally told?

                      Thanks!

                        Yes, it has unfortunately been sawn in half at some point.

                          Hi,

                          Can you post:
                          - larger and clearer pics of the "flat" sides,
                          - one of the bottom lamination of the pic which read 110 CLERGET: it seems there is a letter there, just on the left of the saw line.

                          Regards,
                          PM
