This was compiled by the pre-war shipbuilding research group led by the late Professor Akira Endo. It's a publication from a quarter of a century ago, and is already a rare resource, with copies only held by institutions like the National Diet Library. It has been stored in a dark place, so there is almost no fading or bending, and there are no markings, so it is in good condition. #Ship #Warship #Naval_Vessel #Former_Navy #Battleship #Aircraft_Carrier #Cruiser #Destroyer #Submarine #Ship #Main_Gun #Machine_Gun
