I found the following images on a militaria auction website (
www.emedals.com) and am interested in trying to identify the markings. One of my relatives flew a Fokker at Spich in 1919 and it's possible this is the airframe he flew. If it's not the specific airframe, it's probably as close as I'll get.
Here are the pics:

Wings and Tailplane. The wings and tailplane appear to be in standard lozenge fabric, with the darker variant on the upper surfaces and lighter on the undersides. The underside of the upper wing shows what appears to be a series of patched holes along the line of the rear spar. Perhaps it was opened up for inspection as the aircraft was restored to flying condition? My guess is that the patches are red dope or something similar.
Cowling. The cowling appears to wear the factory finish, perhaps in dark green with lilac patches.
Undercarriage. The wheels are perhaps dark green or red with blue centres. The undercarriage appears much the worse for wear. Aside from the mud, the starboard tyre looks semi-deflated and the wing between the wheels looks damaged. I wonder if the undercarriage was replaced after the image was taken because it was clearly being prepared for flight...and I wouldn't want to take off or land on that undercarriage.
Fin and Rudder. The fin in both images is the same shade as the fuselage (more on that below). In the first image, the rudder doesn't have any markings but in the second, standard RAF stripes have been applied.
National Markings. Standard roundels on the upper wings, lower wings and fuselage without white outer ring. As noted above, the rudder has the RAF stripes.
Fuselage. The fuselage is causing me the most trouble. It looks very clean and fresh, perhaps indicating it's been recovered. The colour is very pale, perhaps indicating clear-doped linen (CDL), pale blue or perhaps silver. To be honest, I have no clue what colour was used. I initially thought CDL but other experts have strongly suggested silver dope.
I'd appreciate any thoughts on whether my initial colour scheme identifications are reasonable. I'd also welcome any additional thoughts that I may have missed.
Many thanks,
Mark
