Luftwaffe EM/NCO's aluminum belt buckle that comes on its original 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 aluminum construction box buckle. The buckle is nicely maker marked with 'A.d.B., L 39', the matching leather tab is nicely maker marked by the company of 'A.D. Baumeister' from Lüdenscheid and dated 1939 being a rarely found manufacturer. It is nicely 'L.B.A.' (Luftwaffe Bekleidungs Amt) marked as well. Nice original buckle in good used condition!
