Nomde, for what it's worth.
I stopped off at the bookstore after work and was looking at the latest "Flypast" magazine.
In it was a photo of Gabby in the cockpit of that Jug. The photo was from the front left side looking back.
Two things jumped out. First was the photo was from a time after the upper fuselage and wing stripes were painted out. Might be a thought since the Schilling "Hairless Joe" Jug and the "Stalag Luft III D-11 are from that time frame.
Second was the black of the fuselage invasion stripes was clearly there, not just OD between the white stripes. There was absolutely no doubt that it was black between the white.
As the magazine wasn't worth the cost, I didn't buy it just to post the photo
