This blog (in true Ronseal tradition named: “Vintage photographs of battleships, battlecruisers and cruisers”) features a lot of very nicely reworked pictures of warships from all over the world and a lot of different times. Some stuff I did not even know existed once upon a time. Most importantly however, it contains very nice pictures of Regia Marina vessels.
