I've got a copy of that book.
A few years ago, I wandered into a second-hand bookshop in Devonport, Auckland, NZ and spied a copy of the book on their shelves. Curiosity got the better of me, so I picked it up and opened it and had a quick browse and ended up purchasing it. You are right, it is an exceptionally good read. Sadly, the bookshop in question closed about four years ago. You could find all sorts of very rare and interesting books in there. Whenever I was in Auckland it was always a good excuse to catch the ferry across from downtown Auckland to Devonport just to see what I could find in that shop.
