RCA CTC-12 estate sale find

[Adam]

I picked up an RCA CTC-12 console at an estate sale this morning. Its one of those big entertainment centers, and I couldn't fit it in my trunk so paid half the price and am having the guy hold it for me until the weekend when I can come up with some way of transporting it.
It has some vert size issues. The UHF dial is jammed. And the back right leg is broken off.
Also only the green gun works. I am a bit worried the CRT is bad, but I would think if that were so either it would not work at all, or the red and blue would be dim but not nonexistant as it is here. If it is bad I do have a spare 21FJP22, but it has cataracts, and the green gun on that one reads completely dead, while red and blue are strong, but the socket is loose, and I bet it just has a wire to one of the pins broken. Actually, I don't even know if this takes the 21FJP22, when I get home I'll have to see if I have the schematics to this.
