A transitional M17 helmet stamped C.A.S. 66 originated as a World War I Austro-Hungarian steel helmet (M1917 Stahlhelm) that was later reissued and used by Germany or other allied/axis forces (such as the Wehrmacht or SS) leading into or during World War II.This is a really nice, excellent example of a WWI M17 Austro-Hungarian Helmet that was converted for use by the Third Reich in the 1930s before the issue of the M1935 helmet. The original “Isonzo braun” paint was removed, and then WWII early war “Apfel-grün” (Apple Green) paint was applied, which is still present with a bit more brown patina. Liner band present but no liner. Comes with Helmet Stand.
