Rick, I am sure you didn't mean any disrespect, but you did link Watson to the original nine (despite that you don't even know if it was him), and quoted someone saying it was a "goat course." You also linked Ross to the project in 1916 but neglected to mention that the plan reflecting the current place was already in existence prior to the Ross visit, and that the "goat course" wasn't anything near Watson's final project. In short, you aren't exactly presenting the evidence of Watson's involvement in a favorable or a complete light. The fact is, the club itself was unequivocal about Watson's involvement, and was quite positive about his design. That is not reflected in your coverage in this thread, although it was covered in your book.
As for open questions, there are of course always open questions. But unless there is information with which I am unfamiliar, the question of who was responsible for the plan at White Bear - a plan still largely reflected on the ground today - there is no open question. According to the club at the time, it was Watson, and Ross and Vardon helped develop Watson's plan.
This has been covered repeatedly.

PCraig, I think there used to be a version of the map posted (by Tom MacWood I think, but I am not sure) on one of the old threads, but I can't find it. Unfortunately most of Tom MacWood's attachments were lost with one of the previous upgrades. Perhaps Rick has a copy.
