Hi, Regia Marina.
There are a couple of important books (at least for me) about british shipbuilding, specially in the second half of the XIX century and the first quarter of the XX. "British Battleships" by Oscar Parkes (is an old book, and very instructive but unfortunatelly I don`t know if there is a modern edition, I own a book of 1973!!. Dr. Parkes is the most tangible proof than a professional in health sciences can be also an excellent technical historian). And a pair of books by D. K. Brown. "Warrior to Dreadnought" and "The Grand Fleet". Cheers.
Very cool. I own a few books on ships (mostly modern ships)that have been out of print since the 1980's. These don't have many plans in them, but some good technical details and pictures. I will look into these.
