The 21FJP22 in my GE made RCA CTC 15/16 clone has a RCA tube in it, but it's of a lower quality than you would have seen in an RCA or Zenith, GE most likely used tubes that RCA rejected, this one has a tiny but noticeable flaw in the shadow mask.

Wow these tubes were far from perfect to begin with they didn’t seem to last very long maybe it’s because of the materials that were available at the time but to call it a defect of sorts for just a mark on the mask.
