^^^ IIRC, FJ plans were for the Constitution class, not specifically the Enterprise as seen under Kirk's mission. I think there was also a disclaimer in the notes about vessels in the class having variations and changes not reflected in the General Plans.
I'd say this gives some leeway in the differences, such as the missing Emergency Manual Monitor.
I still love the FJ stuff, some of the best ST work ever.
Yeah, but as a fan I wanted drawings of the ship I saw and loved onscreen and not some generic unknown. And it would years more before we started to see more faithful drawings begin circulating.
That said FJ's work did add to much of the world building we saw/heard onscreen, the references that suggested so much more "beyond the bulkhead."
Now I have to say that FJ's influence encouraged me to have a similar style when doing my own 2D schematics.
