The lot features four Military helmets from WWII through Vietnam era. First is a WWII era "Brodie" helmet. The Brodie helmet, called Helmet, steel, Mark I helmet in Britain and the M1917 Helmet in the U.S., is a steel combat helmet designed and patented in 1915 by Englishman John Leopold Brodie. Colloquially, it was called the shrapnel helmet, Tommy helmet, Tin Hat, and in the United States, the doughboy helmet. A post-war Belgian-made copy of the Mark II helmet was the M1949. The shell was identical to the British original, except that the liner fixing screw on the crown sat in a small indentation. The liner was of Belgian design and the chinstrap was copied from the British Mark III helmet. The date stamped on interior liner strap is 1952. This is a good helmet in good condition. The helmet looks repainted or never used. The measurements of this helmet are 4 1/2" D x 12 1/4" L x 11 1/4" D. The second helmet is a Vietnam era fiberglass helmet liner with the Steinberg Bros 1973 contract number on the headband; it is in good condition, shows minimal sweat stains, and measures 10.5" L x 9" W x 6" D. The third helmet in this lot is a US M1 Steel helmet Outer Shell, mfg 1941-85. The chin strap is intact but shows wear from use; the steel exterior shows average scratches from normal use and the headband basket is detached. It measures 11" L x 9" W x 6.5" D. Lastly, also in this lot is a Vietnam era M1 steel helmet, metal stamped 71 and ink stamped I-72, in good condition. The headband basket is in good condition with normal sweat staining.
