Thanks Pilot.
Yes I know each jasta had its own colors and design. Did not know the fact about the jasta leaders a/c.
Did the Idflieg directives come before or after some a/c of jasta had special colors/designs? I have the impression that it was thought to be a good idea and should be used by all fighters.
Do you have a date?
I have most of the Windsock publications which show many of the colors and designs.
