Check this out. Cleaned it out of my grandfather’s Massachusetts basement when he passed a few years ago. Feels full.

Appears to date from the 80’s? “Official Olympic torch” gas haha

Should I try to fire it up??? If it’s safe still I’d love to use it!

I had a couple old bottles (not THAT old LOL) and I hooked one up to my soldering torch for some plumbing work and it worked fine. The problem I had was that when I disconnected the torch from the bottle, the valve on the bottle wouldn't seal closed. As long as the the torch was connected it was fine but with no appliance connected it leaked. I set it outside and let it bleed dry and tossed it. Happened on 2 bottles.

Not a plumber by trade but a fierce DIYer

good point. the gas is probably still good but the rubber seal that closes may or may not work as intended.

Likewise, last year I bled and burned off a small amount remaining in two bottles, one from about 2000, the other from the early 00s. On the older bottle, when I removed the torch, it continued to leak vapor. So I put the torch head back on and left the valve open all day outside.

After that, I was advised I could dispose of them at a certified facility for something like $3 per bottle, or, it was permissible to put them in the trash. I put them in the trash.
