I've never seen one of these before. It has a retro/steampunk look to it, appears to be used to heats water.
There are no markings anywhere except for the clamp on the side do-dad, which is for a company that makes clamps for the aerospace industry.
So is it for cooking eggs, an incubator for alien life forms, or what?
It's got to have some value, well-made and shiny!
