This is a nice aluminum Waffen-SS EM/NCO's Belt Buckle (Koppelschloß). This is an aluminum construction box belt buckle. In 1940 the aluminium belt buckles ceased production and the painted steel belt buckles where introduced for all service branches. The buckle features a smooth background with a high relief, embossed SS style national eagle surrounded by the script 'Meine Ehre heißt Treue!' (My Honour is Loyalty!). The buckle is nicely marked with 'RZM 155/40 ᛋᛋ' indicating production by the company of 'Assmann & Söhne' from Lüdenscheid in 1940. The buckle is in used condition showing normal traces of usage and some small surface pitting, it might be an early ground-dug buckle, see photos. This is the last type buckle produced in aluminum from 1940 and extremely rare and hard to find, missing from most buckle collections. Rare original buckle!
