World War I U.S. M1917 steel helmet retaining its original textured olive drab finish and boldly decorated with period hand-painted unit markings. The front displays a white-bordered roundel containing a winged wheel insignia associated with transportation and motor service organizations, while the reverse retains a faintly visible second example of the same emblem above hand-painted “A.E.F.” lettering for the American Expeditionary Forces. The brim is prominently marked “S.P.U. 534 M.T.C.,” likely identifying Service Park Unit 534 of the Motor Transport Corps, a branch responsible for vehicle maintenance, supply, and transportation support during the First World War. Interior retains its original oilcloth-covered liner assembly with felt crown pad, woven net suspension, and leather chinstrap. The liner remains notably complete, and the shell retains its original textured wartime finish throughout.
