Now it rather appears that Matt Jefferies did not like the VFX hangar model. Although the VFX model had only pairs of two windows in the observation corridors, Mr. Jefferies obviously preferred to have pairs of three.
Mere speculation. It's more likely Jefferies was just working from his original drawings rather than trying to match the filming model.
The fact that everything in this hangar drawing is untapered also reinforces the argument that the sloped hangar drawings in TMOST are plans for a forced perspective model.
Finally, one thing that strikes me about all of Jefferies hangar drawings is that the "booths" are shaped just like the shuttlecraft hatch, even with lines that match the places the hatch doors split and where the windows are.
