Boxed Luftwaffe Air Gunner/Radio Operator Badge. Type FLL.

Zinc based and in an excellent, unworn condition. The eagle with all of the dark oxidised finish. The wreath with all of the silver plate still present and some patina. Still in the original tissue paper wrapping.
Not marked but a known variation that has been attributed to the company of Friedrich Linden from Lüdenscheid (FLL). See GCA database.
The fitting cardboard box in a very good, barely used condition. Printed on the top of the lid with the designation „Luftwaffe Fliegerschützenabzeichen mit Blitzbündel“.
Extremely difficult to find full set in best condition.
