Hi Andrew Taylor - thanks for the tips. I'm simply waiting for Elizabeth Wilhide to provide more details and facts. She got a first in PPE at Oxford and has written a large number of very successful books including most design books 'by' Terence Conran so I think we can rely on her facts (which I'll nonetheless double check and reference). If you could possibly give us a few hours before deleting this page, to complete all the work thoroughly on it, it would be tremendous. Thanks.
