As regards the prima facie evidence, the "C" could have originated in the prime universe for different reasons than the Pete's World universe. It might mean Cybus over there, but over here it might mean "Cyberman". Or like the "S" on Superman's chest it may not be a letter of the English alphabet at all. We don't have anything clearly telling us that says, "C on the chest necessarily means "Cybus".

In fact, going by Nightmare alone, I would think the "face value" meaning of the "C" would be "Cyberiad" — a way to mark off those Cybermen from this particular "batch".

But again, we got nothin' narratively.
