At the 1996 OTF seminar in DC, Greg Van Wyngarten (I apologize for the spelling.) and I had a discussion about Stropp while in the WWI wing at NASM. He mentioned that one of the senior OTF members had a piece of the original yellow and green tail fabric and flicked a bit away to reveal underside blue paint! This would be direct evidence that the plane left the factory in painted camoflage.
Other corrections:
1. Shade of the green used ont he metal bits;
2. A stain that would be darker, more yellow than the current.
As for the balkenkreuze underneath, these were originally added in a WPA restoration in the 1930's. Guess it was easier than cutting out eisernkreuze stencils.
