Please educate me as to why a 22" CRT set would be the correct fit for the old cabinet. Is it because the newer crt's were sized larger for its given designation?
Is using a 1" smaller new color crt the guideline that would be used for this type of modification regardless of the original sets size? As an example I also have a 1959 Zenith, model #D2458, using the Super 20 Hi-Fi chassis. The actual viewable diagonal measurement is just under 20". If someone wanted to do the same replacement on this set would a 19" or 20" newer unit be the correct fit? Would using total sq" be a better guideline?

The Sams is from a #615 folder, which the Sams index designates a '63 publish date. The set is probably a 1962 model year. It's a TS570, which is a higher end model, that year.
I don't know if anyone can come up with the dimensions of the original B/W CRT, to compare with the 21V or the 22J color CRT's.
BTW, the original CRT used in that set is a 23AHP4.
