On with the Excelsior. While I have nailed down the exterior of an idealized model, I have yet to fix the details inside. Not for lack of examples. Of course the number of decks and the arrangement has a lot to do with how long the drafter thinks the ship is. Doug Drexler has an alternate to the Ent B MSD, but this one matches what we see on screen (the two side Impulse units and he has them as shuttles). And the way each of these deviate from the studio model itself.... but lots of good ideas, even including the Ingram which I posted above.
