That's a GE-branded rebuild. The saga of this set and its original CRT are here on VK:

To summarize:
The original tube had gone to air.
Scotty rebuilt it and sealed all the usual suspect glass metal joins, but it went back to air quickly after it was done.
I donated it for testing the helium leak detector at ETF, which required necking it again. The leak was found to be a tiny ding in the metal/metal weld between the faceplate assembly and the bell.
When last seen, it was in storage at ETF, marked "Wayne's tube," in hopes that we will have a rebuilding facility some day.
I replaced it with an all glass rebuilt tube bought from Scotty just before he closed down, until this 21AXP22A came along years later.

I should take another picture, as the fine tuning was a bit off, causing the off-color edges on the bars. I didn't notice it that much but the phone camera really emphasized it.
