Gentlemen, Sinisa,

As I told you off, this is a pure provocation. Nothing else. Or, better, no reasonnable other option... And I got the confirmation it is.
As for the emblem: primer? Why not but never seen as far I know primer being coated on camouflage before painting an emblem.
As I told you, too, I strongly believe this rare variation did last only the time to take the picture. Just a try ... until further notice/discoveries showing us for sure another machine with the same variation and/or the same machine on a different shot.
Same for an all white Adamson seen on a 4./JG26 machine.
By the way:
http://don-caldwell.we.bs/jg26/26emblms.htm We can abviously understand why this "variation" didn't last very long: Ugly!
Last, talking about that last "Graue 8". One friend of us did comment: "But yes it's grey .. on the picture"
Best regards, Franck.
