Ha, I was thinking about one of those .... Presentation, nickel plated conductor lanterns .... as I was reading your post.
The mother of a friend I had in college in the 59/60's collected lamps and lanterns and she had a big bunch of them. I use to look them over whenever we were studying together, of course that was long before I ever got interested in "Junk".
Anyway, she died sometime in the late 80's and the younger brother of my friend forced a "split-up" of her possessions and thus an auction was held. And in her collection was one of those
Presentation lanterns and some dude from Baltimore, Md drove all the way to Glenville, WV ..... and he "tooker" back to Baltimore with him but he had to pay way over $1,200 for it as best I remember ........ and
he was happy as a lark to get it at that price
T'was then I first learned they "
are worth $$$" as you stated.
