Thanks. I just asked if it was fore sale. The lady replied "yes but the least he will take is $200" My reply sold! Much to her surprise! She seemed happy to sell it. Someone unbolted the chassis...So I got a huge crash when I loaded it. Also looks like a cap exploded!

20 inch

how zenith does model numbers is number of tubes in chassis by CRT size
so the 22t20 zenith will have 22 tubes with a 20 inch CRT.
this can be confirmed by the tube chart on the left side, of course

That CRT looks like a 21AMP4, aluminized, possibly an RCA.
I hope that CRT isn't damaged. It should be recapped.
The audio can be aligned so it doesn't buzz.

Then it would be a 21 inch, for sure... I think that I found the set (in blond) on the Tv History site: http://www.tvhistory.tv/1956-Zenith-X2359E.JPG

Well, I was going by what he said in this video, https://www.youtube.com/watch?v=6lZIJQ-cKDs&t=354s .

about Zenith numbers, right /wrong no idea, he seemed to make sense though.

But as I mentioned, the CRT# should be on the CRT, and the tube placement chart, and should remove all doubt?

I don't consider Shango to be a great authority on things. His indifferent tone of voice troubles me, sounds like he couldn't give a zip how things turn out. Fix it or trash it, seems not to make any difference to him.

Yes, Zenith chassis in that era did use the code #tubes, year, CRT size.
However CRTs at the time and size range tended to be odd inches, 15, 17, 19, 21, 23, etc. Also the chassis could be used with a small range of CRT sizes, to that same chassis would work with a 19 inch or 21 inch CRT for instance.

Indeed, a list of Zenith model numbers and some chassis numbers from the 50’s show no exact correlation to CRT size: http://www.tvhistory.tv/1950-59-ZENITH.htm
