M1911 Preussen Schirmmutze (M1911 Prussian Infantry EM/NCO visorcap)
The Prussian army’s visor cap evolved from the enlisted mans "stable cap" in the early 1800's and was originally reserved for wear by Officer’s and Senior NCO’s with enlisted personnel being outfitted with a visor-less "Kratzchen" type field cap. In the early 1900's wear of the visor cap was extended to EM’s and Junior NCO ranks when off duty or in peace time. In 1907/1910 the German army introduced a new field-grey uniform, including headgear, to replace the previously worn dark blue uniforms. In 1915 after the outbreak of WWI the new 1907/1910 uniforms and headgear underwent minor modifications and were re-designated the M1915 uniform. On its introduction the NCO/Officer’s visor cap was issued with a branch of service, (waffenfarbe) colored centerband and piping. In 1917 the visor cap was modified by discontinuing the branch of service color centerbands and replacing them with a less visible green centerband for all branches of service but both versions of the caps were worn concurrently.
