This is an old piece we inherited, that was probably picked up in England in the 1950s. The closest thing I have been able to find to it is an old egg coddler, which features a burner under a pot, similar to this. But this does not appear to be an egg-coddler, as it has no inner cage to hold the eggs. I have extensively searched Martin Hall & Co. pieces, and have found nothing like this. So the first question is, WHAT exactly is this piece?--What was it designed to do? The measurements are as follows: --The Tripod legs (shaped like tree limbs) are 15" tall. --The silver pot that hangs suspended by a chain, is 4" high x 4-3/4" wide. --The burner at the bottom of it is @ 2-2/3" across, and opens up for fuel, and an opening and closing cap on top. Speaking of the burner, what sort of fuel is this supposed to use? Does it need a wick? I realize this is not sterling, but is plated, but because it appears to be so rare, I'm hoping it will be worth something to collectors. Could you please give us an idea what it's worth? Along with the photos I took, I am attaching one from a website that shows clearly the exact marks that are found on the bottom of the pot, just so you can see what these are. Thank you for your kind assistance in helping us figure out what this is, and what it's worth. We really do appreciate your help!
