Model 1916/1917 Stahlhelm
The Model 1916 helmet was developed in 1915 to counter the effects of countless head wounds due to der Stellungskrieg (trench warfare). The helmets were first issued for field testing in Dec 1915 to the 1st Assault Battalion. The trials were so satisfactory that an initial issue of helmets was made by Jan 1916. Unlike the Allied helmets, the German helmet used a very high quality chromium-nickel steel and afforded superb protection to the neck and ears. The helmet weighed approximately 1 Kilogram (2.2 Lb.) and was issued in six sizes 60 to 70 in 2 cm increments. The size of the shell is stamped onto the rear of the apron. The size could also be determined by the two ventilation lugs on either side of the temple area.
These lugs are found in four sizes and doubled as mounting posts for a heavy forehead shield. This is the lug for helmets size 66 and 68. This is the largest size commonly available, although there is evidence that a small quantity of size 70 were manufactured.
This is the lug for helmets size 64.
This is the lug for helmets size 60. This is the smallest size of helmet.
The Model 1891 chinstrap posts from the old Spiked Helmets were retained for use on the new helmets.
The liner band was manufactured from thick leather, and held onto the helmet shell with three split prongs. Three liner pads were sewn to the band.
Each liner pad had a small pouch on the reverse for padding. Each pouch was tied with ribbon, and filled with horse hair.
In May 1917 the helmet was modified by replacing the leather liner band with one made of sheet metal. This was made necessary by the leather shortage at that time. The Model 1891 chinstrap posts were retained. The new helmets with the metal bands were designated Model 1917 Stahlhelm
