Lastly, it occurs to me that we also see the U.S.S. Intrepid.
and with an NCC-registry of "1631".
In my NCC thread
an interesting piece of detail turned up (post # 125) according to which the registry of the Intrepid
was originally to become "1707" in ST IV.
Which makes the TOS-R scene in "Court Martial" rather interesting. Does the "1631" really belong to this Intrepid
(it's not on the starship status chart because it reads "1831") or another starship, instead?
