Aptiveboy, if you like those 6" 53s, there are two of them, outside the South end of Cromwell Hall (the gym) at Subbase New london. At least, they were still there, >10 years ago, when I last visited.
As to Flyingfish's deck, it's not so odd. I have Portsmouth drawings that show, that style deck. It was standard enough that the drawing is a "Basic" drawing, not for a specific boat. I believe it was the deck layout for used Amberjack, (as built) with two 5" 25s.
Lastly, Rokket; if you, or anyone else, want to know about my time on the boats, you'll have to ask specific questions. I have no idea where to begin, otherwise.
