Here's a pretty rare vintage Gas Camping Lantern made by King Seeley for their THERMOS division. Unfortunately, it was "electrified" by some unknowing flea market vendor and what you see here is the result once I removed the "improvements" he made. Holes were hacking into the steel fount/tank that could maybe be patched by a skilled person. Also the generator is gone.
It's a Model is 8321 and is commonly referred to as an Inverted or Donut Lantern. It's upside down compared to a standard Coleman lantern with the mantle and globe on the bottom and fount on top. Not sure of the age but believe to be late 50's to early 60's.
Original globe marked PYREX THERMOS. If you need parts or can fix the holes, this lantern is a deal.
