Fliegerschützenabzeichen with Blitzbündel

[AlecH]

Gentlemen - I was offered three Luftwaffe badges at the weekend, one is this Luftwaffe Fliegerschützen Badge with lightening bundle, I don't know to much about Luftwaffe badges. The makers name is stamped on the back B& N over the letter L - unfortunately the catch is bent down not able to open the pin.What do members think the material is ? is the badge good / bad ? Any information welcome. I'll post the other one a little later.
Regards

I think this is a good one Alec! Wait for some more opinions from the Luftwaffe collectors but to my semi trained eye it looks original. Many features seem to match the badges I've looked at, even down to the tiny flaw on the reverse of the wreath, just above and to the right side of the hinge.
