M1917 Steel Helmet US Army 17 Co 110 Engineers 35th Division named !

the division's shoulder patch, a Santa Fe cross in a circle, was conceived as a marking for division vehicles and baggage in 1918, and was first promulgated by 35th Division General Orders Number 25, issued on 27 March 1918. It was officially approved for the 35th Division on 29 October 1918 by the adjutant general of the American Expeditionary Force. The marking was later stenciled onto signs identifying the whereabouts of division units, soldiers' helmets, and finally was made into a shoulder sleeve insignia when that usage was authorized.
