Thanks a lot Oldeskewltoy
Unfortunately, the yellow-green tables are still unreadable.
I dont know if they contain important information ? The only way translations of Japanese for me is OCR software then online translator.
I am not able to prescribe these stamps, in Poland we call them worms.
In any case, in spite of better quality tables are still unreadable.
Whats more I have the impression that there are not many strictly technical data.
I found a few interesting books which may contain a lot of information, unfortunately, I am unable to purchased even single one of them. They are unreachable.

But it is good anyway because they are suspension diagrams - this will help a lot. I still have a quiet hope for blueprints but those diagrams are a lot better then nothing - so Im glad.
