Not exactly a camping item, but i picked this up and the lady told me that miners used it to keep their lunch hot when they went into the mines, but i have done some searching and never seen another one. its made by Landers, Frary & Clark, and the patent date is Mar 19, 1917. anyone that knows anything more, I'd appreciate the info.
