Martin,
A few years ago, Melvyn Morrow emailed me some pages from the Old Tom Morris book you refer to that cover Leven-Lundin and have details about the composite course before the separation. I lost the email, but I might have the printed sheets.
I really envy your membership there. That is just a fantastic club and a wonderful course--one of my favorites in the world. The hole I love particularly is, I believe, the 2nd, which has the option of playing a drive straight ahead into a little valley, where your approach shot is semi-blind up the hill or, playing your drive long over a ridge and getting rewarded with a fine angle to the green. It's a basic strategic hole, but I really found that one special. The 18th and the Circus hole were just wonderful as well.
