Re: NCC-2541 is canonical
To my knowledge, the large Excelsior model only had the following applied to it...
NX-2000, USS Excelsior
NCC-2541, USS Hood
NCC-2000, USS Excelsior
NCC-1701-B, USS Enterprise
NCC-42768, USS Lakota
The Hood's registry first appeared in a graphic in TNG and later in the Encyclopedia.
The model that Jein made had a few registry numbers applied over it's career, though I only have photos of it as the USS Excelsior (NCC-2000), USS Fredrickson (NCC-4211) and USS Excelsior (NCC-2000 put back with missized decals).
There was also the Excelsior class Melbourne in DS9's "Emissary," which would either have been the original studio model or a model kit.
