Hi Tim,
I just searched for the book title using AbeBooks search function. I was really looking for an old copy or the reprint. Not finding any of those, I noted that SN Books World had replied with their details for the digital reprint with leather binding, etc. They quoted fifteen quid for the book and ten for the postage. I PLACED the order for the book with AbeBooks, who confirmed it , then passed it to the bookseller, SN, who then passed me their invoice through Paypal. I paid it using PayPal as I do with a lot of internet purchases so felt pretty safe. All went pretty smoothly.
Cheers,
F.
