Growing up we had a "Mill End" store downtown which had a lot of milsurp. Bought a couple anti-exposure suits and a C-ration brownie that was pretty good actually. They also had plenty of ammo cans. A few years before they closed forever, there was a ton of stuff from Europe--Germany especially--East and West. Gas masks, web gear, medals, badges, helmets and wool blankets. You could find the store's six-toed cat easily, she would camp out on a stack of blankets.
