WH (Luftwaffe) 'Flakkampfabzeichen' (Flak Artillery War Badge ). The Flak Artillery War Badge was introduced by 'Reichsmarschall Hermann Göring' on 10 January 1941, for award to air defence crews including searchlight and sound detection personnel. The badge is a nice 'Buntmetall' example, the badge is not visible maker marked. The pin and catch are complete and functional, this is the type with the so-called ball-hinge Nice original example in very good condition. The best example I've found from this type, this comes out of my personal collection!
