Thanks Warren, Rick, and Stephen - another step closer....
I finally received the Misterkit paints I had been waiting on...and decided not to use them! The Albatros red-brown was too light for my liking and the Fokker Olive Green was way too bright. I ended up using Tamiya XF64 red-brown and Pollyscale Fokker dark green. I think it looks pretty good - it may not be perfect but I'm certainly happy with them. If anyone has any details of matches they use for the early colours I'd love to hear.
So here's how they look now....

The D.I wing is the one with the CDL patches left for the upper wing crosses. All the other crosses were applied directly on the CDL too and had no white background or edges.


The D.II fuselage was masked with tape, but all the rest was done with a piece of thin card, torn to give a slightly ragged edge, held close to the surface to give a not-quite-definite edge. I'm happy with how it's turned out although there's a little bit of touching up to do in places.
Of course I had to do a quick mock-up with the wings on.....

Thanks for looking in!
Ian
