Aluminum buckles with worn by some Luftwaffe Generals (the open faced claw buckle style was also worn).

These are new, very good quality reproductions.

Note!
These will not fit the standard EM, Tropical or M44 belts. The officer belts are designed differently and must be custom made- the "female" hook must be sewn in. This piece is included, but you must know how to make your own belt- unless you only wish to display the buckle on its own.
