Schlueter M1 Steel Infantry Helmet Liner and USMC Camouflage Cover | eBay
The shell and liner are nothing special. I am more interested in the USMC cover than anything else, even Korean era covers are apparently really hard to find; especially in Oz.
Already up past $80. This will probably go for a lot.
Even though I may have just increased competition; to bid or not to bid?
