"And interesting that the signage isn't original."
I'm not saying it is not, it's merely not on Mr. Datin's "label list" (which is not complete anyway).
Looking for older photos where you could see more than what had been on TV I came across Allen Asherman's Star Trek Compendium
which had a VFX shot of the flight deck which revealed more on the starboard side but wouldn't show where the indentation ended. That might have been the inspiration for the "Warning Fire" model recreation.
And can somebody please explain this http://tos.trekcore.com/hd/albums/1x...sevenhd022.jpg
compared to this http://tos.trekcore.com/hd/albums/2x...abelhd0046.jpg
(and not three or four observation deck windows as in TOS-R).
