Original Item: Only One Available. This is a very nice original French WWII Model 1926 Adrian infantry helmet, retaining substantial portions of its olive green finish, original-style liner, leather chinstrap, and the distinctive circular RF flaming grenade infantry badge mounted to the front. The liner is clearly size marked 56.

The front of the helmet carries the traditional French infantry insignia consisting of a flaming grenade bearing the letters RF, for République Française on a circular background. The flaming grenade was the established branch emblem used on French infantry Adrian helmets. Different branches of the French Army employed their own helmet insignia, including crossed cannon for artillery, a bugle for chasseurs, and other specialized devices.

The helmet retains its original liner which is in good service-worn condition, and is made from a tan leather. The size is stamped on the liner, 56. The chin strap is still present, stretched over the front brim due to the leather shrinking, but it is still quite pliable.

The Model 1926 Adrian, or casque Adrian modèle 1926, represented a significant simplification of the famous French Model 1915 helmet introduced during the First World War.

The original M1915 Adrian had been developed in response to the enormous number of head wounds caused by shell fragments and falling battlefield debris during trench warfare. Introduced in 1915, the Adrian became one of the first modern steel combat helmets adopted and issued on a massive scale, preceding the widespread appearance of the British Brodie and German Stahlhelm patterns.

The M1915 was a relatively complicated construction assembled from several major sheet-steel components, including the crown, brim sections, and separate crest.

The M1926 retained the unmistakable Adrian profile but simplified and strengthened the design. Most importantly, the principal shell and brim were stamped as a single piece of steel, eliminating the joined brim arrangement characteristic of the M1915. The ventilation system beneath the comb was also revised, replacing the earlier large opening with a series of smaller ventilation holes.

These changes produced a simpler and somewhat stronger helmet while preserving the low weight and distinctive silhouette of the original Adrian.

The Model 1926 became the standard French combat helmet of the interwar period and remained in widespread service during the Battle of France in May and June 1940. It subsequently continued to appear with Vichy French, Free French, and other French formations during World War II.

Overall, this is a strong and substantially complete example of the French M1926 Adrian infantry helmet, retaining its characteristic one-piece steel shell, raised comb, RF flaming-grenade infantry badge, size 56 liner, leather chinstrap, and considerable surviving olive green finish. The honest wear to the paint, liner, and chinstrap gives the helmet the appearance expected of French field equipment that remained in service through the turbulent interwar and World War II periods.
