WW2 German Helmet's Rubber Ring, rare

WW2 German Rubber Ring, used to fix different camouflage elements on the helmet. This example was removed from dug up helmet. The ring itself in perfect condition with clear visible maker's markings on it. The rusty spots could be easy cleaned, but on our opinion it's looks better in uncleaned condition - more attractive! Factory made example, special issue to use with the helmets.  Extremely rare item of ww2 field gear.  Do not miss.
