Hi: I have a 1975 Sylvania tube manual open, and it lists on pg 512 "short" specs for the 19TP22. The base is 20A, same as the 15G, deflection angle is 60 degrees, max second anode HV is 20 KV. Reading this drives me to speculate that it IS a larger version of the 15G. I'll try to find more in depth specs, but many of my books are packed away due to renovations. Next week, I'll look in the library at the Vintage Communications Museum in Windsor CT, and post any further info I can come up with. It seems likely that this tube was obsolete very quickly. Probably just as well, at least from a practical standpoint, but it would be interesting to locate an actual TV in which the 19T was used.
A good mystery is a great way to keep the mind active. Kevin

Courtesy of the Early Television Foundation, I am posting this page from the CBS CRT manual, which lists more complete specs on the 19TP22. Thia is available on their website, and I thank them for posting it. Hope I'm not stepping on any toes by including it in this post.

The 15GP has the flat screen with deco mask. The 19TP from the above GE info is not listed as having a flat screen...so it can't be a larger version of the 15GP, can it? But the Raytheon shows a deco mask, so would that indicate a flat screen? I'm confused.

I've seen the SAMS folders for similar sets, but it was quite a while ago. The museum referred to has an almost complete collection of folders, and I'll sit down with an index to try to find at least one set using the "mystery tube".
After the Army, I worked for a time at a distributor, and would read folders while eating lunch lol. Saw many interesting things in all those folders. Kevin
