Tuscaloosa will not match any San Francisco config exactly. The 4 main structural differences were; First, the lower set of bridge face windows was slightly lower than on San Francisco. The space between the communications deck and the pilothouse level was 11' 8". On Astoria, Minneapolis, and San Francisco, a raised deck was added 3'8" above the original comm deck and those three had the front glassed in at that level. Tuscaloosa was glassed in at the lower level. Second, the 5" gun positions on the main deck level - most of the class had the middle gun on each side inset slightly closer to centerline, while Tuscaloosa had the aftermost gun as the inset one. Third, on New Orleans, Astoria, Minneapolis and San Francisco, the searchlight tower straddled, fore and aft, the vent between the stacks. On the other 3, the tower was narrower fore and aft and rested entirely on the top of the vent structure. And fourth, the vent behind the after stack was a single rectangular structure on San Francisco, but Tuscaloosa had two smaller vents, which curved over toward the stern, with a small deckhouse between them.

Finally, Tuscaloosa, because she spent most of the war in the Atlantic, had a completely different 20MM arrangement, which varied over time. (Guns were added or moved during the brief stops between deployments.)
