Camouflage colors are Model Master enamels; Dunkelgrün RLM 71/ Grau RLM 02 splinter and Hellblau RLM 65.

As for the markings, the decals in the 1975 kit weren’t all that sharp, and they were stuck fast to that 40 year old “protective” waxed paper they came with anyway. I had to try something else. The new tool Airfix 109E in my stash came with alternate German and Bulgarian insignia, so I raided that kit’s markings for Franz von Werra’s Battle of Britain aircraft.

I don't agree 100% with the 1965 Profile Publications rendering (the colors and pattern of the wings camouflage and the red on the spinner, for example), but the painting is still inspirational!
