Cased Luftwaffe air gunner badge B&NL

Stunning cased original Luftwaffe air gunner badge or Fliegerschützenabzeichen mit Blitzbündel. The badge is nicely marked B&NL indicating production by the company of Berg & Nolte AG, Lüdenscheid. The badge is constructed out of the early Tombak material and lightly marked on the back with a name on the back. The badge is in good condition without damage or repairs. The case is in very good condition with working button and most if not all of the blue finish externally. Very nice and collectible badge, hard to find in good condition!
