I also wanted to add that I found an old thread here where it was said that this cross references to an ECG561. https://www.videokarma.org/showthread.php?t=262454
There is a used one on eBay, but I'm a bit wary that the pins being labeled differently, namely 2 of them labeled FOC instead of one being REF. Could anyone confirm that this correct?

Be careful of that one. It may be for an EFL CRT, that would have 2 focus
terminals. EFL is "extended field lens" or "tri focus CRT" big difference
is it has 3 focus grids. VERY bright & sharp. Came out in H chassii on
high end 17 & 19" sets. 13" & 25 " were added in the L chassis.

Interesting... how old are the first 3 grid focus (2 adjustments) CRT? I see that are used for monitors, also (in person I've seen only last era TV's and monitors using it***).

EDIT, NOTE: ***(since I worked only in the early 2000's with TVs)
