Thank you folks!
I am aware that this a/c had three different styles of crosses. The side cross (thank you Cliff) clearly shows an overpainted white square. So we have the standard Fokker style with Eiserne Kreuze, after that Eiserne Kreuze with the regular 5cm border and at last the Balkenkreuze. But I do not understand why we are looking at the 2nd and 3rd versions...it should be all the 3rd version, the last version. And I still do not undestand where the middle cross with the curvature white borders was applied.
Drdad, I am pretty sure that I took these pictures from this side sometimes ago.
CWatson, I am really wondering why this triplane is guarded. I never saw any other guarded german a/c, the only ones I saw are foreign a/c forced land outside of airfields. What was the reason for this? Preventing souvenir hunters after the demise of MvR...?
