I do have some personal pics I downloaded many years ago (for personal enjoyment) concerning the failed attempt at a Battlestar Galactica Tech Manual. I'm refraining from re-posting the pics at the request of the creator.
I found them originally at TFXart by Mike McAdams. Ken Thompson was also involved with the project.
Here's a link I found. About 3/4 of the way down you'll find a partial Viper cutaway. Not sure how accurate it is, but it's quite interesting.
