Did you ever finish the Gunslinger ll ?
The only story of The Scot's I was involved with was Shiloh. I know he had notes for some sequels like Apache Nation but they were never passed on to me. I got involved with his work to finish Shiloh because he had some serious real life issues at the time, and they are on-going. I'm in intermittent contact with him and will pass on your interest in Gunslinger II but that's all I can do at the moment. Sorry.
