I don't recall anyone establishing the OTM elements. Could you point me to that thread? If I recall correctly you relied heavily on the sloppy club history or maybe it was Kroger (who relied on the club history too). From my research it is clear the original course was designed by Archie Simpson, not OTM. T. Simpson apparently redesigned the course in circa 1908 (he described the changes in an article in 1909). He didn't build a new course, so naturally it would still have many of the original elements.

You covered all your bases there, Simpson advise was probably unsolicited and/or Fowler was probably lying. Where else did Simpson give unsolicited advise?
I agree with you about the Cruden Bay's history, but despite the many errors everyone seems to accept its account, including Sean.
I'm more optimistic, I think we are much closer to the truth than we've ever been. Archie Simpson laid out the course in 1899 (his masterpiece). OTM gave some advise. The resident pro A.N. Weir polished up the course in the early 1900s. T. Simpson or possibly Simpson/Fowler redesigned the course in 1908.
I'm not sure what Simpson's relationship was with the Club, he clearly had some relationship based on the two articles in Golf illustrated. The second article was reporting on the big professional event played their in 1909. The Great Triumvirate were entered, and I believe Taylor won it. T. Simpson was the referee for the tournament.
I don't know if Fowler was a frequent visitor or not, but he did play in at least a couple of tournaments at CB in the early 1900s. He may have had a relationship with the Club too, which why I think its possible he was involved in 1908.
