Award identification

I'm going through a new Luftwaffe soldbuch, and came across an award that for the life of me I can't read or make out what it is. Does anyone recognize the circled award? Many thanks for some help!

It's the Flak crew sleeve patch. The entry says:

Tätigkeitsabzeichen d. [= der] Flakart. [= Flakartlilerie]. Battr.Bef. [= Batteriebefehl] Nr. 21
[signed]
Oblt. [= Oberleutnant] u. [= und] Batterieführer"

...i.e.:

"Trade Badge of the Anti-Aircraft Artillery. Battery Order no. 21
[signed]
Oberleutnant and Battery Commander"

Thanks HPL! I looked through every badge and clasp I could find for a similar looking match, and never would have thought to look for a patch. This is the first time I've come across one listed. Quite interesting.
