Tony, thanks for the info! I like this find, nice conversation piece!I would say that it had a bottom which finally burned out . It's A pot designed to fit into the large eye on a wood cook stove. It would get hotter and cook quicker. I have kettles made the same way.
Could there have been some kind of removable plate that went inside? Seems like it would slide in to a wood stove holeLooks to me that the bottom has a finished edge, so a double pot steamer/strainer doesn't look likely.
Picktime is the closest... through your money in and it falls right out never to be seen again lol
