I just ran downstairs and took a two quick photos of the Sopwith prop I have, which is the design AD644. I need to take it down and get a better image of it, but you can see the general shape even though the angle of the camera distorts it. If you search for images of Camels on google you will see this prop fairly commonly. I suspect the Aussie one is the same, but I've emailed the seller and suggested that he include any stampings in his description.

The AD644 prop is 2590mm with a pitch of 2650.

That's a fascinating decal, and really shows why the decals themselves have become collectible in their own right.

Spoke with Mr. Wille at St Croix. We are going to look at doing a replica propeller.

Let me know how it turns out, and I can take high resolution photos of decals now if you want them.

Will do and keep you in the loop; he wants to know the static rpm on the current 90 x 48 blade first, so will know next month.

Bonjour Pierre-Michel,

Can you tell me the G number, bottom left in the photo. I can't quite read it. I'd like to add the details to my database.

With kind regards,

Bob

Hi Bob,

G number is 1207 and serial is AD 644. I sent you pictures of this prop about one year ago (march 2009 ?) : We unsuccessfully tried to read AID boxes (one is "?IV", but others ?).

Regards,
PM


Edit : Oooops ! "?IV" and not "?ID", as first written !

Default Ruston Proctor Prop shop

The subject application is a replica Ruston plane. I would imagine that if Ruston had their own prop shop, they probably used their own Lincoln Imp logo.

The well documented Ruston 1000 plane looks to have the AD644 design. Do we know that Ruston made AD 644s?

I have also read that Lang props were preferred by Camel pilots in the field. True?

Many thanks Pierre-Michel. I had forgotten. And I have all the data in my database!

Those AID stamps might be 91V. This was an inspector at the maker Aldam Heaton, but I only have records of them making BE2, BE12 and FE2 props. But they were still making props in 1919 so might well have made Camel props.
Unfortunately there are quite a few AID nos with 9 followed by two letters, so it might also be 9IV. I have recorded both and in some years time Might have the answer.

With kind regards,

Bob
