Well, I don't know. The two pics I posted in #10 are still there, and naturally I can't find the one of the WWII fleet boat plotting table or remember the exact search term I used. Google is well named because that's the number of useless unrelated hits it returns.
One problem in finding photos - when I was in the Navy there were many restrictions on even the possession of a camera, and an AX had a lot of background checks and security clearances involved, "burn before reading" all that stuff. I got out in 1982, and was rather shocked to pick up my first Tom Clancy novel only a few years later revealing a lot of the classified info I knew when I was on active duty. Apparently it was declassified and I hadn't heard about it.
WWII was undoubtedly the same, all this stuff was probably so top secret there was very little in the way of documentation or photos available after it was declassified. Mark 14 with the Mark VI exploder was a good example, so secret that when the war started all the submariners tasked with maintaining, prepping, adjusting and firing the torpedoes were scratching their heads trying to figure out a new system nobody ever heard of with no manuals or training. SNAFU.
