Wehrmacht (Heer) Belt Buckle (Koppelschloß). On 24 January 1936 this new pattern EM/NCO’s belt buckle was officially introduced to replace the previously worn Weimar era Reichsheer buckle. The basic design of the Reichsheer buckle was retained with the addition of the new Wehrmacht style national eagle. This pattern buckle was worn through-out the Third Reich period with minor manufacturing variations and different colored finishes. The colored finish was determined by regulations depending on what form of uniform it was to be worn with. This is a nice 2-piece aluminum construction parade style box buckle with a pebbled background, the separate frontplate is attached with four prongs. The buckle is maker marked with 'OLC' indicating production by the company of 'Overhoff & Cie' from Lüdenscheid. Nice original early parade style buckle in good used condition!
