Hi Jack

Although you have a lot of info there about the propeller, there is nothing to link it to a specific airframe. I am assuming at this point that those details match a Clerget Camel, Perhaps ‘Annerac’, a valued poster on this site will reply.

So many props were disposed of as surplus after the Great War that it may not even have been fitted to a plane. To link it to anyone, you would have to have some other provenance such as a named photo album etc, sold at the same time.

Sorry not much help.
