  • Requesting info and value of propeller

    Well, as the title states I have inherited this prop from my grandfather. Now, that it has been stored (somewhat poorly) I am trying to figure out what to do with it.

    The background story as I know it: From what I know my grandfather bought this prop sometime around the 50's or 60's. The story I was told, is that a friend a of his at the time had just purchased the building that used to be home of the Wright Bros Manufacturing warehouse. While the two men were digging about the junk that was lying about the building, they came upon an old carpet buried under various boxes and debris in the back of the building. Rolled up in the carpet was the prop that now sits in my garage. That is what I know about this prop, and that information is only as good as my mothers and my own memory.

    When I was younger I remember reading the sticker on the prop that said Wright Brothers Co. on it. I think it was blue at the time. Now, it has cracked and turned brown due to poor storage conditions. Some it is still readable, but may require a magnifying glass. It has stamped into it US12 9 2 7 6 and 8C27924 on the front near the bolt pattern. It measures 9' 2" long, 11 3/4" across its front as it lies, and 7" thick. It also has a small (1" square roughly) four leaf clover (?) stamped into it between were those numbers are located. From what I have been told, this prop was never put on a plane.

    I am at loss as to what to with this thing. I saw the sticky saying not to restore something like this, I'm not sure if a collector would want it or not. So, that's why I came here, to get the opinions of some people who know WAY more about this then I do. I don't even know what kind of plane it was made for, so please remember you are talking to a complete novice in this field.

    Any suggestions or information on the prop would be greatly appreciated! After looking through the pictures info available I'm kinda overwhelmed. Even pointing me in the right direction would help. Thanks for any help!

    More info

    I saw this on this site and I think there might be some relevance. The markings are very close as is the style. My prop is almost a foot longer and Doesn't have anything from Liberty on it. I do have to wonder if the two are related.

      The only things I see that may be identifiable although not too helpful is that 8C27924 is most likely SC27924, a US Army Signal Corps serial number that doesn't help at all to id what the prop was used on, and the four-leaf clover which is most likely a signal corps inspection stamp. If there are no witness marks on the hub indicating it wasn't used it may be from a plane that was converted to use metal adjustable props thus the wooden one becoming obsolete.

        I just found a similar looking prop from a shop near Normany France. It has the similar stamps SC 57433 & U.S. 12. & 9'2"

        It looks identical to your photos.

        I have no idea what aircraft it was used on or what the value of it is...does anyone have any idea what it's worth?

        Thanks,
        Mark

          Requesting info and value of propeller

          Attached are two photos of an older propeller for sale here in Germany (was found near Normandy France). The only markings on it are No. 2795, SC 57433 (which I believe stands for Signal Corp & model #), U.S. 12. 9'2"X

          The only other visible marking is a small square with the number 712 and an arrow inside the square. This square and number is located just outside the center hub.

          I don't see any manufacturers name anywhere.

          Do you have any idea what the prop would be worth. It has been used, but looks in great shape (some wear on the leading edge of prop at the ends).

          Appreciate any info anyone might have for type of aircraft it was used on or thoughts on value. I've also seen a lot of posts advising NOT to restore. Is it best to leave "as is" or is it OK to put some wax on it?

          Cheers,
          Mark

            "U.S. 12" refers to the Liberty engine, and the length of 9' 2" is consistent with that.

            It's value is substantially less due to its condition, bu in original varnished condition I'd guess around $2500 or so.

            You can't determine the aircraft unless tha info is stamped on the prop, but that design is seen on aircraft like the DH4.
