I only see one tube/TV that would work according to your chart, a 1983 19" Sanyo 91C530, with tube number 19VMFP22. Is that it? That's the only TV/tube that will work on a 4900?
If you come to town to buy my brothers WOW I will toss two in, I will have to double check to see if I have some burn free or low burn but i thinkk I can find 2.
