Doesn't look like it was ever used... maybe once or twice. Great find! Just goes to prove, they're still out there, just have to look a little harder! Very nice, indeed!
I don't think it was ever fired. The mantle got burned in and that was it. That lantern is a hard one to find. It's even harder to find it with the 990 globe intact. If you decide to use it and want to prevent the globe from being broken, you can buy the 5177 tapered globe like you find on Elite propane lantern. That globe will fit the 331.
