Thanks all for the kind words. For photo reference, check out Lance Bronnenkant's excellent _The Blue Max: Airmen, vol. 1 -- Boelcke and Immelman", particularly the photos on pp. 53-55. The lower wing and rudder were clearly painted with some some of experimental technique (perhaps at the front?), similar to what one finds on the Jasta 5 Albatros D.IIs and D.IIIs. Colors are unkown (something lighter dabbed/stippled over the usual greens and browns/rust).
The wood panels were done decals are by Proper Plane, with a little bit of enamel painting, shading and dabbing to enhance the decals.
Happy modeling,
Jason
