A completely random question - does anybody here know ALL the variations of the Enterprise NCC 1701 model? I mean I know the original Cage model had those spiky things on the front of the nacelles, then sometimes they changed the back part of the nacelles (in some shots they looked like lightbulbs, in others completely different) and of course they built a completely new model for the movies, but does anybody know what changes and when were done to the original model? I noticed only the changes on both sides of the nacelles, but I think there were more of them
