Sony definitely made a 24" Trinitron monitor: http://www.amazon.com/dp/B00004YNSR/
and a 34" widescreen TV: http://www.amazon.com/dp/B0002NDFKM/
CRTs that large were pretty rare, though. Monitors tended to stop at 21" (by which point they were a good foot deep, if not more...), and I'm less certain about TVs, but I'd be surprised if even 34" ones were all that common. If nothing else, they're an absolute bugger to move. My parents' 31" widescreen CRT was an absolute monster... my back still twinges just thinking about it.
And a Trinitron too! That must have been spitefully expensive to buy...
