Hey, this looks great. I noticed the new source of traffic on my site and anything named blockade runner is likely to get my attention.
I was the one who created the deck plans for the Nebulon B for West End Games' Star Wars Roleplaying Game. It was for a book called the Far Orbit Project, which was a Nebulon-B - the campaign centers on the ship. While not every deck was included, many were, and more than the couple of images I have on my website portfolio. There are also written details about the ship itself. I should also point out that when this was created, it was not intended to be the exact "Medical Frigate" of Empire Strikes Back, but one of a similar type. It had more in common with the Xwing video game version. That said, I made sure the medical bay had a window appropriate for the ending scene of Empire.
You should pick up the book (it is still available through sources at amazon
). It has parts of decks 1, 2, 4, 6, 7, 9 and 16. It has all of the forward sections of decks 5, 8, 11, 14, 17 (bridge, which is on my site), 18, 21 & 26. It also has aft deck 9 (engineering, which is on my site). Each has a graphical scale, so you can actually measure the different decks. Though, as you already know, there's a lot of eyeballing shapes and sizes on this ship because of the irregular shapes.
It is worth noting that the size and number of decks were not determined by me, they already existed, as did some of the ship's general arrangement. They were given to me, and originally came from the Medical Frigate Section in the Star Wars Technical Journal
. The number of decks vs length of ship meant the floor to floor height of the decks was on the low side. I was also given a list of what to include on each deck, so while I designed the arrangement in plan, there were other sources involved.
Also, at the time (back in the late '90s), I could find no shot of the starboard side of the ship model in any movie or still. The only reference was from the X-Wing video game. The movies always show the antenna side (and even flip the image in RotJ).
Good Luck. And I'll plug this forum and blockade runner on my weekly Star Wars Wednesday blog.
