Offered is a Luftwaffe Flak Badge, made of zinc and attributed to Gustav Brehmer. While this example is unmarked, it is a well-known variant that matches the design and construction characteristics of Brehmer-produced badges.
 
The front shows excellent detail with a crisp eagle and gun, and no visible wear. The pin and catch system is fully functional, making it suitable for display or wear.
 
There is some zinc pest (zinc rot) present on the reverse, as often seen in zinc-based awards from this period. The pricing has been adjusted accordingly, making this an affordable opportunity to add a genuine example from a desirable maker to your collection.
