The paint scheme is just aluminum and some other color, I guessed RLM 02, it shows up differently in the few photos available. The original flew for a short time, and a second
was built that never flew, it had some differences and was furnished with operating retractable gear unlike the first. There is a video on the internet of it flying, not very clear.
It looks to me like on that flight the aft canopy was not fitted.
The paint scheme required a lot of masking tape and paper. I tried to enhance the panel lines with a sludge wash, but the lines were too faint. As it was a wood wing,
and the lines do show up in the silver areas it works for me.
It struck me as I was finishing it that without modification it could have had a part in the Disney "Planes" movie.
