This authentic pre-war Luftwaffe belt buckle is crafted from aluminum, a material commonly used alongside brass and nickel silver during the period. The buckle shows significant wear, with noticeable softening of the eagle, wreath, and pebbled background due to extensive use.
The reverse side is maker-marked "Ad.B.L." and "39," identifying the manufacturer as A.D. Baumeister of Lüdenscheid and dating the piece to 1939. The accompanying matching leather tab bears the markings "A.D. Baumeister 1939 Lüdenscheid" and is stamped "L.B.A." (Luftwaffe property issue). The tab has been rethreaded with what appears to be period-correct cotton leather thread.
In excellent condition, this buckle typically commands a value of $350 to $400 due to its rarity and desirable maker. Given its good overall condition, it remains a highly collectible piece.
