FWIW, the Nav station on the USAF C97 was actually behind the Capt. seat on the aft part of the flight deck.
Maybe, but the BOAC ones that I worked on had a route to the co-pilots seat BEHIND the engineers panel, he passed the F/Eng and turned left behind the panel, and the Nav followed but turned right down a step ( or Two ? ) to the cubicle on the Starboard side beind the rest of the flight deck.
