My 21CT55 (CTC2B) has a 21AXP22 and has never lost it's vacuum. I understand that the set originally came from the Las Vegas area to Omaha and has been moved around locally, and still has really good emission. Although It was replaced with a "new" 21AX in 1957, so the original must have crapped out a few years after the set was built.
