I have this item that was sold as a Luftwaffe engineers collar tab a long time ago. As an Iron Cross and Combat Badge guy I am not particularly informed about collar tabs. I just have a few cloth items hanging on my wall. Upon playing around with a blacklight recently I noticed that this tab really lit up, compared to my other few Luftwaffe collar tabs. Oddly however, only the pink material lit up, all the threads, piping and white and tan backing did not glow under blacklight at all. It also seemed to pass the burn test when I burned a small thread, for what that’s worth. My only concern is, that this is a bright pink color that could possibly glow under black light due to the color itself, not because it is made after the war. Someone more knowledgable on these may be able to identify at a glance if its legit or not. I just want to make sure before I get rid of something authentic based on false info.

The one photo is under black light, and black light doesn’t photograph well just took it to illustrate the glow, so sorry about the quality.
Thanks
