Luftwaffe M40 Single Decal Combat Helmet (Stahlhelm M40). The steel construction M40 helmet retains most of its rough textured, blue-gray paint and about 85% of the decal, the decal has probably been moved during the application, something which is more often encountered on helmets. The other side of the helmet strangly looks to show some faint outlines of a decal however M40 helmets regularly don't have a second decal. All three liner retaining rivets are intact. The interior of the helmet is a M31 leather liner with all eight fingers intact, the leather is still supple, the liner is a size '57'. The liner is missing its original liner cord. The liner ring is 1940 dated. The shell is marked with maker and size 'Q64'. 'Q' is indicating production by the 'F.W. Quist, G.m.b.H.' in Esslingen. The reverse interior neck guard apron has a stamped lot-number. The helmet is complete with its original brown leather chinstrap as found together. The chinstap is nicely maker marked and dated 1936. Nice original Luftwaffe helmet in good condition!
