I think it pretty much boils down to what Username1 said, and said rather well. In addition I would add that it all could have began with the trip to where you got it and from there to your home. A 24" is a pretty big tube and a set gets turned in all sorts of awkward positions and such when people try to move them. Then there is road/car vibration which is really bad on glass.

All of these things all the way up to tightening that band a couple of years ago could have led to that fateful day. Maybe a flaw at the factory 60 years ago behind all these things and all these years and then the ride and vibration and the tightening of the band. Oh, and the temperature changes or better yet one too many episodes of The Rifleman. Or maybe none of this is true and it was shot by a random drive by shooter and since there is no air conditioning there only remains a spent projectile that got vacuumed up and nobody knows the difference. Seems there was mention of a gunshot, or the sound of one.

OK, wow! I get more like Arlo Guthrie the older I get! Being a little silly, but why not have a little fun. It's a pretty far out story.....
