Super rare helmet here in very nice condition. These were part of the Special Attack Unit Program during the war and were worn by “Suicide Sub” pilots. Only around 6200 of these boats were ever produced making these helmets pretty scarce. The helmet is reinforced with a heavy steel front plate and is stamped with a naval style anchor painted on the front. The inside of the helmet is in even better condition with a complete liner, drawstring and chinstraps. The chinstraps even appear to have blood on them which is pictured.
