Also some itiner for the Hiraga archives if you want more on oyur own:
I'm going to post a method I've used successfully to get from the homepage to the images. The images - especially those of the ships plans are well worth spending time looking at and there is a lot of detail in the drawings.
Again, I recommend using Firefox or any other web browser that will open the image files full size. MS Explorer only gives a small window to peek through. Once You've opened the images you can zoom and pan.
1. Go to the Hiraga Archive homepage - here is a link to it at the University of Tokyo website.
http://rarebook.dl.itc.u-tokyo.ac.jp/hi ... ode=logout
2. Click on the big red button at the bottom of the page this will lead you to a page with a grid on it (the first page of the archive) at the right there is a column of blue buttons - click on the top one and this should take you to a page which has a thumbnail of a graph of Mikasa's speed/power curves. In the middle of the link there is the number 20140101
http://rarebook.dl.itc.u-tokyo.ac.jp/hi ... VlJg%3D%3D
This number identifies the image.
3. Replace that with the following numbers for the following plans and hit enter
For B61 - 22053001
For B62 - 21930101
For B63a - 21930801
For B62 B63 A B C D E F G design comparisons - 21930201
For B64 - 21930301
For 'A' - 21930401
For 'D' - 21930501
For 'G' - 21930601
Each of these should bring up the page with a thumbnail of the image you are trying to see.
4. Click on the thumbnail and it should open in a new window that lets you zoom and pan.
Good luck and sorry for this confusion!
