I know that when I used to go to Dunbar CRT Rebuilders in Los Angeles in the 80s, for "while-I-wait" bonded glass removal, they would remove the glass first with a hot wire between two handles, and then use a banding gun to apply the band. It was an air-operated gun; similar to the ones used in palatizing of machinery for shipping. I happen to remember the name "Signode" on the gun. I don't think it was anything special for CRT banding, but I don't know that for sure.
I'm glad you didn't get hurt (seriously), and I'd say you had an anomaly implosion. Once in a rare while, I used to hear about TVs imploding in the middle of the night in unattended rooms (no people, pets, earthquakes, nor objects that could have struck the tube). Your tube probably had a weak spot in the glass, which was protected from uneven pressure all those years by the safety glass. Once exposed to air, it failed.
