i've had plenty of 1940's sets with bad CRT's, so many in fact I'll probably never find enough good tubes to be able to fix them all.
The good ones were probably either low hour sets or had the CRT replaced shortly before being take out of service.
There wasn't as much stuff to watch back then so they probably weren't turned on at Breakfast and turned off at Bedtime the way some people do nowadays.
New sets have hour counters built in, they usually will tell you the number of times the set has been cycled on and off too.
Even this 2007 LCD monitor I'm using on my PC has an backlight hour meter on it, it has a bit over 9000 hours right now.
