Hi Hamish, Barry is spot on with his comments. The most revealing book for me has been Owari to no tanko and Markus Sesko's fab translation
It is necessary to have the the two books. Next I would look at the Haynes catalogues from the early 80's even though the pictures are mainly
black and white and his opinions are criticised by some but most love him and won't mater to you one way or another, look don't buy yet.
All these books can be got from Grey.
Alan.
