Ww2 German flak combat badge, so-called “Ball Hinge” piece, lacquered on the back, in a case
Absolutely original fine zinc flak combat badge, so-called "Ball Hinge" piece, version with the silver burn varnish finish on the back.
The badge is in condition 1, the back is sealed with varnish. Variant is called "ball hinge" because of the ball hinge. Manufacturer unknown, the unmarked piece identical to the pieces of the marked A.S. in the triangle of ISAs. Thus, the idea of at least "Ball Hinge" is the manufacturer A.S. to ascribe well possible.
However, this is speculation and not confirmed.
