The one above is at least 35 years old and at one time could be found at any small hardware/general store in France. Not sure when they went to the collared design but good riddance to the old style! I once expected to be arrested when I removed a half used, hissing cannister at an airport and tried to discard it!
Many many years ago a local camping store was going out of business. They had a closeout sale and by the time I heard about it, almost everything was gone but the remaining stuff was pennies on the dollar. I bought an adapter that uses the puncture type canisters on a threaded type stove. At that time I had quite a few puncture type canisters in storage. I had misplaced my Bluet stove, so I had no way to use the canisters.
A few years ago I decided to get rid of some of those canisters. Used that stove adapter and a modern stove on a trip. I recall hearing at some time that if you put a piece of tape over the puncture on an empty canister, it does not stink up your pack as badly. Thus, the tape on the canister on the right. And I taped the canisters together to reduce the number of things to pack every day.
