Thank you Michael,
Your information is much appreciated, It's a great shame that few people realise the great historical value of such books and as you say they could just be dumped to rot away. Sorry to be so long in replying but I've just got home from a days Pre Operation Testing for when I go in for Surgery next week for Bowel Cancer. Keep your fingers crossed for me please.
