Yes. I have done some more scrutinizing.
I have been able to get some registries for these ships:
* U.S.S. Excelsior
* U.S.S. Yorktown
* U.S.S. Endeavour
* U.S.S. Apollo
* U.S.S. , NCC-30352 (this ship is under repair at Starbase 74)
* U.S.S. Yuri Gagarin
* U.S.S. Excalibur
* U.S.S. Lexington
These ships were the easiest to get registries for.
I am nowhere close to getting the names for five of the ships.
