Luftwaffe Visor Unit Markings?

Hello all!

I am a 14 year old collector relatively new to cloth German headgear. I recently bought a pre-war Luftwaffe signals visor. It is a private purchase cap, and it has what looks to be unit markings stamped onto the sweatband. Can someone give me some help on identifying these markings???

Attached are the pics of the cap and markings
