Hey Wiley, I know you request no reference pics but I may have discovered something interesting and wanted to show these for discussion's sake, (not that I want to high jack your thread either). In Insurrection there is a scene where the Enterprise fires two aft torpedoes at the incoming Son'a, even though aft launchers aren't physically modeled in until Nemesis. However, I may have found the launcher on the Insurrection model anyways.
When Picard and Worf are leaving the Enterprise there is an object protruding just below the red stripe before the large set of windows. You can see it has a definite Shadow and almost looks like it could be a launcher. But I have never seen a reference pointing it out as such and it only appears to be a light in First Contact. Perhaps it is just a light, but when I seen it in Insurrection a moment ago it made me do a double take. It would certainly explain those two torpedoes in the film.
You can ignore this of course if you think it's irrelevant here. I just thought I would share and see if anyone else noticed.
