^Or, we could just say that the 71807 registry is the real one, and the other two were just mistakes or changed premises, which was what the producers decided anyway. And it's not like this kind of thing hasn't happened before. The Hood's original registry labeled on its saucer in EAF, was 2541. But various computer displays read 42296, and that is the accepted registry. Similarly, the Zhukov's registry labeled on its saucer was 62136, but it's real registry was 26136.
IMHO, accepting that mistakes were made and premises were changed is far better than trying to come up with convoluted leaps in logic to justify production flubs.
