Hello friends! I acquired this Luftwaffe tropical side cap from a friend in trade. His grandfather supposedly brought it back from Tunisia. I am not well versed on German cloth uniform items. The eagle is very salty. There are numerous sweat stains inside. Neither the eagle or the stitching glows under blacklight, and, well it smells old too.There is a square printed mark on the inside but it is very hard to make out. All I can read is the size 60 underneath. Any opinions would be appreciated!

Color is a known Luft tropical could be Berloina maker stamp. timothy
