The notifications seem to have stopped arriving . . I'm not ignoring you . . honest !
As far as I know, the metal work for the sternpost, cockpit area (including cowling attachment ring and machine gun mount), undercarriage legs (although stbd legs are from a different Pup), fuel/oil tank, and wheels are all original parts.
I have feeling that the tail empennage is also the original, I'm not certain on that, but I will check with the owner.
There are a few fuselage fittings and control horns which were in a reasonable enough condition to be re-used, and are original to this aircraft as well.
The fuselage woodwork has been replaced using the original timbers as patterns, some of which appeared perfectly O.K. but were too old to be trusted to flight, and were certainly not acceptable to the PFA (now LAA). The upper wooden cockpit decking is original, when sanded down the 1917 camouflage paint was revealed. The identification of our aircraft was by means of the manufacturers' plate attached to the airframe.
The wings are not original . . we are making them at the moment
You could be right about some parts having already been replaced before Kel found the thing. His restoration is listed as "rebuild 2" in the CAA records. The previous rebuild is not recorded, but we do know that the Pup was re-engined by the RAF in 1918 . . could this possibly have been "rebuild 1"?
The aircraft simply "dropped off the planet" in 1923 when it was supposedly disposed of when the RAF took over the Claude Graham-White aircraft factory, where it had been languishing since it's last flight at the Hendon Aerial Derby in 1921.
We have anecdotal evidence that there were two Pups in the Graham-White hangars in 1923, but as yet we have been unable to identify the other one. Although I have a theory about it, and if anyone out there has information on RAF Andover, specifically No 7 Group Navigation Unit from 1920 to 1923, I'd love to correspond with them.
There are lots of questions surrounding this aircraft, which I feel will unfortunately remain unanswered.
Hope this helps.
