it is out of order, but the page numbers are on the page, so I have printed it out to look through it.
The writing style is very dated and difficult to read (a lot of the technical words have been romanticized (katakana) since this time, so a lot of odd words). With this and the one flying example left, you could restore it (it is the dream to have one of the restoration groups in the US purchase it back and restore it) and fly it. It has been mistreated a bit since the 70s, bit it is in better condition then a lot of the Japanese planes.
