Original Item: Only One Available. This is a striking original Imperial German WWI M1916 Stahlhelm, maker-marked Si.66, retaining approximately 80% of its exterior feldgrau finish together with its original M1917-pattern steel liner band and all three leather liner pads. The helmet exhibits a pair of corresponding perforations through the shell consistent with a projectile or shrapnel strike, with damage continuing into one of the original liner pads. The alignment of the shell and liner damage makes this an especially interesting surviving example of a helmet that appears to have sustained its damage while assembled.

The helmet still has both of the dome headed chinstrap retaining rivets, which hold the interior pickelhaube style chin strap lugs in place, and one end piece of the chinstrap is still retained on one rivet with an interesting piece of twisted wire over it. The shell also retains both of the extended ventilation side lugs, which are the correct short version without any step for the larger size 66 shell. This would ensure proper installation of a Stirnpanzer brow plate regardless of shell size.

The helmet is stamped next to one of the chinstrap bales Si 66, for the maker Eisenhuette Silesia, Paruschowitz Oberschlesien. This is a relatively uncommon maker to find, as they only produced shells in sizes 62 and 66. Size 66 is a nice large size that can accommodate liners from 58cm to 60cm or US 7 1/4 to 7 1/2. There is a rolling mill mark dome stamp of B i 458, indicating that Bismarckhutte in Oberschlesien made the steel. This is the usual dome stamp for an "Si" marked helmet.

The three liner pads are retained on the M1917 metal liner band. One pad has some damage from the piece of shrapnel or bullet. This is interesting to find with the original liner still attached.

The German M1916 Stahlhelm entered widespread service during 1916 as a response to the severe head injuries caused by artillery fragments and battlefield debris. Its deep skirt, substantial side protection, hardened steel construction, and characteristic ventilation lugs represented a major departure from the leather Pickelhaube. The Stahlhelm was primarily intended to reduce casualties from fragmentation rather than to provide guaranteed protection against direct rifle fire.

This helmet is particularly noteworthy for the combination of its Si.66 Eisenhütte Silesia manufacture, Bi 458 Bismarckhütte steel stamp, large size 66 shell, original feldgrau finish, correct unstepped Stirnpanzer lugs, M1917 steel liner band, surviving leather pads, partial chinstrap, and corresponding shell-and-liner projectile damage. The relationship between the perforations in the steel and the damage to the surviving liner provides an unusually direct physical record of the helmet’s history, while the untouched maker and rolling-mill markings document its manufacture within the Imperial German wartime helmet-production system.
