I fully respect the fact you don't want people injured by shoddy workmanship however the bottle that ruptured by your own admission was not an A&M Custom gunsmiths one, and so far none of them have been.
Unfortunately i think there has been some scaremongery by the gun club and gunsmiths that saw your QF bottle
yes the best fittings QF did rupture in your thread, however as the thread says only 6 were made and most failed
