Very nice original Luftwaffe Flak badge in good condition. Made in silvered tombak or buntmetall. There are no markings, but this is the unknown maker version documented on pages 228-233 of Marc E. Garlasco’s “The Flak Badges” (2008). The clasp is a touch loose and the wire loop is a tiny bit wiggly, I didn't feel it necessary to play with it too much. I just left it the way it came to me.
This is a really beautiful badge and I'm only letting it go to put some money back in the badge fund as there is a tunic I am trying to complete.
