WWI United States Army 17th Infantry Division painted Brodie Helmet. Helmet bears the correct seam on back of rim, period marking under front brim which reads "FKS-4" , period liner & O-ring with period swivel bevel for chin straps. Helmet is also marked "105 U.S. INF. A.E.F." in what appears to be black paint just above bevel stud on right side of helmet. 17th Division's Insignia appears to be hand painted in black and red paint (which shows craquelure consistent with age) on the frontal upper brow of helmet, as all WWI soldier's were not given formal division insignias. This item bears all period hallmarks and markings coupled with patina & aging consistent with age this item is in overall excellent condition considering aging, wear & storage.
