Re: 3 Registries for the Yamato?
or NCC-71807 was the hull's original number and the NCC-1305-E was placed on it during commissioning. During that small span, the Yamato was overhauled and received its original number.
I have always wondered on what the Galaxy-class hull that would become the Enterprise original hull number like NCC-71825.
