Sorry for the awful quality of the following shots, they were taken from a 1996 interactive movie game called Star Trek: Borg. The game was set aboard the USS Righteous, an Excelsior class ship "destroyed" at the battle of Wolf359. The storyline is complex and irrelevant to this thread, but these shots show a mid-TNG Excelsior bridge.
Not suggesting you use them for reference, as it has not been unusual to see two similar ships with entirely different bridges (Enterprise-D and Odessey, for example). Just thought I'd post them out of interest, TechTrekker reminded me of them.
