You're giving this one hit wonder a big head... (But seriously, I'm very flattered, thank you.)
I used this as my primary reference:
http://home.wlu.edu/~overholtzerc/swguides/images/isdschm.jpg
The basic shape, angles and porportions are taken directly off this diagram. There are several places that are not consistant with reference photos of the studio model (Ex: The rear profile of the neck is too steep), I eyeballed a lot of that sort of thing.
The reference photos can be found at various websites, most notably at:
www.starshipmodeler.net
I found some rather large, high res shots that have been very helpful, but don't remember where I lifted them. If you send me an e-mail, I'll forward them to you.
Good luck, and please post picture once you get going!
