Hello guys I have read this article...and I have a question about the Visor Cap for Air Traffic Control : The officer's schirmmutze then have the piping in Apple green with the silver chincord ....and not have the classic silver - piping for all officers of the Luftwaffe ?? Is the unique case in the Luftwaffe which the officer's schirmmutze wear their branch-colour piping ? Thank you...very interesting thread
