Rare tabbed Aluminium Luftwaffe belt buckle in field grey paint by Franz Reischauer 1937

Pre war 1937 dated Heer tabbed aluminium belt buckle. The belt buckle is made by Franz Reischauer in 1937 which is a rare to encounter manufacturer.  The buckle has completely lost all of its paint on the front but has been period field repainted with dark grey paint. Very nice and interesting example!
