Perhaps RCA continued their prewar policy of selling "lesser" CRTs to competitors and holding the best for their own sets.
The 15GP22 in this set was built in the 13th week of '54.

Must be a manufacturing defect, right? I don't see how it could happen afterwards. I thought the imperfect CRTs ended up in test jigs, but was there ever a 15-inch test jig? I'm guessing not.
Good luck, I really hope your picture tube is functional.
