Les,
So far a very it's a interesting read, lots of spindle work and ideas.
More than that a good rescue. While looking for it I discovered that the American Library has declared it a 'Book of Historical Importance' and have reproduced it. However I was able to find an American selling a 1949 first edition copy at what I considered a very good price with a near pristine dust jacket, so I freed it from it's impose exile and brought it back home.
As an aside, the image on the front is of the a Scottish Tulloch Mazer. I've no idea what that means unless it's what we now call a Tazza.
