Hi Mike, sorry about the delay, l don't often log on here. If you give me your email address or some way of contacting you l will gladly send you what l have. I have all the clues from 1968 plus a few from 1969, and some other bits. If you want the routes l can produce both from memory - just don't ask me what l had for breakfast this morning, l have no idea!
Looking forward to hearing from you,
Ken.
