A discussion down there --v or up there --^ reminded me CO2 cartridges
come in a least two connectors, threaded and not. I've been caught by this.
Why the difference? Who cam first?
Years and years ago there was a device consisting of a glass bottle
with an attached CO2 cartridge, called a "siphon" was used to make
carbonated water for mixing drinks.

I believe that the original CO2 cartridges were threadless.
Having a peer about I found

Which is compatible with both threaded and unthreaded. Good idea imho
as non threaded are cheap and easily available.
