This was when I was a kid, 1970's Tv was a late 60's 23" or so, really nice
floor model, all knobs on right, with speaker under the knobs, light up channel
changer knob, number in the middle - if anyone remembers the years for that...

The set shown has a safety glass, so a hit from the front wouldn't have broken the CRT. It would've broken the safety glass, which was tempered glass, like auto glass.
Your uncle's set, was probably a B/W set, with the tension frame CRT. It was probably a stress crack, which happened occasionally.
I'm sure, many of you heard of CRT's imploding, even when the TV wasn't on or no one was in the room.
