Prussian EM's M1915 'Pickelhaube'. The M1915 pattern was introduced on 28 June 1915, the expensive brass and German silver fittings on all issued helmets were changed to steel to free up brass and silver needed for the war effort. The steel fittings were not painted, they were chemically oxidized to give them a flat non-reflective finish. The helmet is complete with it's original liner in very good condition, the helmet is size '55' marked. The helmet is nicely maker marked by a manufacturer from Berlin and looks to be dated 1915. The helmet is complete with it's original black leather chinstrap. The helmet is unit marked indicating usage by a soldier within the 'Infanterie-Regiment 22'. Great original example in exceptionally good condition!
