I had a win recently. I did a swap with a mate (Series One enthusiast.) I ended up with a a very nice original August 1949 Operation (owners) Manual in great condtion. He got a very nice original workshop manual.The illustrations are first class as well as the humerous drawings of a Pom in a tweed cap getting himself into trouble.
If any of you early 80" fans need an owners manual and happen to have a '51-53 (Edition 4 or 5) manual, let me know.
