A Swiss military combat helmet, identified by its distinctive profile and liner system as a post-war variant of the Model 1918 design, likely an M18/40. The shell is constructed from pressed steel with a flared rim and is finished in a matte grey-green paint. The interior is fitted with a traditional Swiss pattern liner, consisting of a leather band with five perforated leather flaps, which are secured at the centre by a white cotton drawstring. The liner assembly is suspended from the shell using metal clips and incorporates rectangular foam spacers for impact protection. The chinstrap is a three-point system made of tan leather with a metal prong buckle. The helmet is fitted with a removable fabric cover in the TAZ 83 Alpenflage camouflage pattern, featuring bold splotches of red, green, black, and tan. The cover includes integrated loops for the addition of natural foliage. One of the leather flaps of the liner bears the stamped numerals 54, indicating a head size of 54 centimetres.
