Tony DeGiulian at NavWeaps had some suggestions for sources

Tony DeGiulian, from NavWeaps.com, had a suggestion for the source that would have weights for gun directors and included some example weights. He says that the source for director weights is John Campbell's book Naval Weapons of World War II. I never had any interest in this book until I found that I needed weights for fire control directors so that I could better calculate metacentric heights for WWII ships. I may need to consider that for WWI ships, as well, but hadn't seemed to need that information.
