Sort of, but not all in one place and you'll have to do some homework yourself.
Many models listed here (some might be missing for all I know):
http://www.tvhistory.tv/1950-59-ZENITH.htm
Manuals listed here (same caveat):

Tube data listed here:

The manuals are listed by chassis number, not model number. If you look at a Zenith manual such as that for chassis 23G22, you'll find near the beginning a list that cross-references about 15 model numbers and chassis numbers. Elsewhere in the manual you'll see what CRT a particular chassis uses. Other manuals have more info.
So, you can look at some pictures and say, "Hey, I love this model," and with luck, figure out what chassis and CRT it uses. Then, using the third link, you can look up the CRT's data sheet and read the description to find out if it has a metal or glass envelope. Or, it's possible the manual itself might mention what sort of envelope the CRT has; I haven't read all of those manuals from cover to cover.
