[ Drawing of Mikasa ( displayed in 船の科学館 (Fune no kagaku kan (Museum of Maritime Science )) ) ]
This drawing was reproduced from 「日本海軍艦艇図面集（昭和造船史別冊）」: "PLANS OF SHIPS OF THE IMPERIAL JAPANESE NAVY - HISTORY OF SHIPBUILDING IN SHOWA ERA"(published in 1975). Probably it is only one of commerce in fine size in Japan. Unfortunately, the original drawing is not clear.
Fune no kagaku kan (Museum of Maritime Science) has other clear drawings of Mikasa ;
(1) "ELEVATION of UPPER WORKS and TORPEDO NET DEFENCE" (not inboard view)
(2) "PLATING PLAN - PLATFORM DECK AFT -"
(3) "PLATING PLAN - PLATFORM DECK FORWARD -"
[ PLATING PLAN - PLATFORM DECK FORWARD ]
(4) "GENERAL ARRANGEMENT - SECTIONAL ELEVATION -"
(5) "GENERAL ARRANGEMENT of STEAM STEERING GEAR "
(6) "POSITION of SEA CHEST &C ON SHIP'S BOTTOM"
(7) "INTERCOSTAL STRINGER above MIDDLE DK"
(8) "ENGINE ROOM CENTRE LINE W.T. BULKHEAD"
(1) and (4) are reprinted in "連合艦隊1905" (published in August, 2011), in small size. You can see contents of the book in Amazon.co.jp, but the drawings can not be seen there.
The parts of drawings are also printed in "BATTLESHIP MIKASA" (booklet by Fune no kagaku kan (Museum of Maritime Science )).
Moreover, the copy of (4) seems to be displayed in Museum Mikasa at Yokosuka.
Yamato Museum (Kure Maritime Museum) has another drawing of Mikasa;
" GENERAL ARRANGEMENT - PLATFORM DECK -"
All these drawing seem to be made up to 1904 ( or completion of Mikasa, maybe) .
About other drawings of Mikasa, I will post another article later.
