I suppose that is a date code on the CRT base, but I can't decipher their mystical scheme.
The other signs point to a low-mileage set. The cabinet is like new. Apart from replacing a couple of small tubes, the only evidence of service (if you can call it that) is where the thermistor broke into pieces and the repairman twisted its leads together to replace the inrush limiter with a short circuit.

Probably so - all the RCA CRT replacement guides I have (starting in 1963) all show the RCA replacements to be 21FBP22 A, the 21FBP22 is likely the original. I have no clue as to the difference between the non-A and the A.
