I'm assuming he's building the A since it's in the thread title. But what version of the A?! Personally, I am in the minority in saying that I like the A bridge from ST:TFF. It's clean, simple, and bright.
Ya- I'm curious which version too... There are so many from movie to movie. Changes to the bridge. Engineering. Shuttle decks.
Actually, a good source for images would be Trek Core's screen caps section. Lot's of great reference pictures there!
