Also there is a certain amount of looking back at 1975 as if people then had the knowledge of 2023. Franz Joseph worked with Roddenberry and Jefferies on designs for Genesis II. He had the opportunity for input. Whatever their later opinions - probably colored by seeing him as a garage entrepreneur they gave free rein who later hit the jackpot much to their dismay - they were originally fine with what he was doing. So that approach of altering exterior and interior to make it all fit didn’t seem to bother the people who, you know, actually made the show. At least until much time and many dollars later. And I don’t know what anybody else thought but I was never ever bothered by getting plans for ships we’d never seen. I thought I’d hit the proverbial jackpot - as if I was seeing material from unseen episodes of the series. And in a way, we were.
