David (and any other interested parties),
You might want to see if a local academic library could to a search on the
OCLC database for you. It's an international database of library holdings. I
know it includes holdings for the British Museum; maybe the articles could be
ordered from overseas. It may cost you a pretty penny, but it shouldn't be
much of a hassle on your side. (I hope.)
And hey, don't tell 'em I sent you!
