Luftwaffe EM/NCO's blue coloured steel belt-buckle that comes on its original natural coloured leather tab (Koppelschloß mit Lederwiderhalt). Originally the EM/NCO’s buckles were produced with a silver finish until a blue/grey version was introduced around mid-1940, and a tropical olive drab version was introduced in late 1940. Nice blue-grey painted steel example, both the buckle (B&N-41) and the leather tab are nicely maker marked by the company of 'Berg & Nolte AG' from Lüdenscheid and dated 1941. The buckle is showing minor traces of years of storage and is in overall very good near mint condition. Stunning original buckle!
