Interesting guess. Phil: is there a date code on the 15GP22? The earliest known by me is the fourth week of 1954. If this tube is earlier it could be quite a significant 15G.

Very interesting set, what is that big circular plug near the RGB imput?

If you're talking about the big plug near the red, green and blue-colored rings, I don't know what the plug is, but those colored things look like test probe points.

The large round plug appears to be a twistlock AC power connector...

What a find and a half! You sure have landed a real rarity there by the sounds of it! Looking foward to the restoration story when you get to it.. Congrats!

The largest connector, beneath the black and white test points, is the power input, a three-terminal Hubbell twist-lock plug.

We know of a total of 6 of these that have survived.

If that date code is correct, there are older 21AXP22's out there. The one in my 21-CT-55 has 4-52.

And the gun was either assembled "rodded" or wired 9 weeks earlier (5-13).

Don't really matter when it was made, its STILL Kewl as all H3ll, one of the best scores I've heard of since the "Prototype" set... This is almost as good as findin' a 1903 Ford Model "A"....Yes, they DID make Model "As" B4 1927...Henry couldn't bring himself to follow up Model T w/a Model "U" or "V", so he started over...

I have an RCA TM-21 that was purchased from NBC in New York about 30 years ago. It was FULLY restored to PERFECT working order by Herman Reynolds III and Bill Cushman in 1987. The only problem with it is that the anti-glare glass that attaches to the picture tube has started to separate.
