My copy was shipped by Ron on the 18th & arrived today (28th). I used his "headscope" web site & payment was by credit card to a PayPal account which took care of the currency transfer issue.
As for the book at this point all I can say is wow! In terms of narrative & style it puts our stuff to shame. It's not a book you're likely to haul around to meets or take out to the shop because it is that elegant. You can construct your own checklist from the info in the book, and after handling wrenches you'll want to wash up before touching that book.
If I can use a dining analogy, the book is like Wedgewood china compared to our Melmac.
As for coverage of the topic, after a quick skim, I can't think of a British nut wrench I'm aware of that is not in there. I say nut wrench because it does not go into pipe wrenches.
I'll have my copy on display at the MVWC spring meeting, so if you're coming to York you can see for yourself.
