This is another feature where the New Orleans class members varied. Well-known is the difference between Mark 9 guns in �round face� turrets and the slimmer Mark 12 guns in �flat face� turrets. The other difference is less obvious � were flat vents added to the turrets in the thirties. These appear on all class members except of San Francisco, but most units had them on sides below the local fire directors. Quincy had them slightly (1/2 of width) more forward compared to the others, but Astoria was another exception as she had them located on the back side of the turret.
Matt / Kraken Hobbies kindly printed these turrets for me in 1/700. There were some visible printing layer lines on turret faces that I tried to make less obvious by liquid putty. The one missing barrel was lost to the carpet monster, waiting for Matt kindly providing a replacement.
Both masts were completed using my PE details. The SC radar, a weathervane and TBS antenna are missing, will be added later.
Did you solder the main bridge components as you did for the mast? if so the soldered joints are flawless, and considering how small is the bridge that's a remarkable feat. 
). The catch is what if the ship was camouflaged, e.g. USS Vincennes in the Ms12 splotch camo, that one would like to use masking tape for. If the hull plating/decals are applied first, which is what my conservative part is suggesting, I�d be concerned about peeling of the first coat of paint - or even the decal! - while removing the masking tape. Using a matt coat for the decal instead of gloss may be an option how to improve the adherence of the paint. The other possibility is to do the painting first, exactly as on the Astoria. Vincennes even had less portholes so less area to avoid. What are your thoughts?
