And the 22KP22 was in the 21" rectangular RCA and the Zenith color sets of the late 60s. Not sure about the 21VBEP22, but it has the same socket as the 22KP22 and likely is a newer version of that same tube...
And yes; the 11SP22 is the "huge dot" portacolor tube. The 11WP22 is slightly "less worse" and was in the later tube PortaColor. Even the last solid-state PortaColor of the 90s with the AB-C chassis had an inline tube with huge pixels.
