Why don't you contact the Librarian at the Royal Philatelic Society of London
http://www.rpsl.org.uk/home.aspThere is a link to their Library and you can search their catalog online. An inquiry to the librarian will probably let you know of any fees involved in their searching and scanning for you.
(If you were in the US, I'd recommend the APRL or the WPL as starting points)
