There was a lot of swapping going on among the manufacturers. Before Zenith had its color crt plant running they used rebranded RCA tubes. I have seen a Zenith rebuilt round tube that with a Sylvania EIA #. Going along with what Julian mentioned with that Admiral tube in a Zenith box, I've been sorting through thousands of tubes over the last couple years and often have come across a tube which looked to all the world like a NOS tube but was the wrong brand. Was it really a pull in that box, or just labeled wrong? Most were RCA boxes with "red ink" tubes for various brands: Zenith, GE, Magnavox, Admiral.
Anyway, I think it is a 100% safe bet that Zenith wouldn't let a set leave the factory with an RCA label showing on the crt.
