I snapped a few pics of my N1 maquette castings, and here they are!
And, yes Hunk a Junk, there were gear doors scribed into the maquette. If I recall correctly, the landing gear was to look similar to the Queen's ship landing gear - kinda' curved and pointy.
I also included a door for loading R2 from below. My "logic" for that was that he was oriented sideways, with one shoulder facing forward.
Since his head could rotate all around, he didn't need his body facing forward after all.
The original drawings had a more flat bottom. I added the "boat-hull" bottom as well as the chines (or winglets) along the fuselage edges.
I still have the original wooden model tucked away somewhere (I'll see if I can find that too). It has the wings coming straight onto the body without the curves at the wing root. It shows how the design developed as we went.

Sorry I couldn't do a straight side view - the foreground engine blocked the fuselage contour.

You can see the straight rifling on the torpedo barrel in this shot (as well as bubbles in the leading edge of the casting

).
