There are actually other issues at play. Pressure vessels have to conform to particular specs (DOT, I think) to be shipped. It may be that they can be filled but not shipped and I understand from one source (one of the largest Halon recyclers in the world) that there is NO actual shortage of either 1211 or 1301. I'll only add that I searched long and hard to find a good Halon 1211 hand-held for the SS car and will use the same stuff in an onboard system when I upgrade it.
