If you are serious, get some Vacseal on the seams, it is $$$, but it may save it!

I'm pretty sure its a 21AXP22, most of the tubes are original dated 56-48 etc.

IIRC from the CTC-5 I converted, the plastic insulator shroud for the metal tube (clearly visible in the photos) doesn't fit over the glass tubes.

Collectors who have vacsealed 15GP22s have experienced vac sealed tubes go down to air....Whether they applied it properly and also got the brass evacuation nipple under the base (which is the one commonality of the all glass color roundys I've seen go to air as well as a common thing on older metal tubes) or not is not known.

Vacseal may or may not have any effect.
