Bob -
Please put my name in Rich's hat for the drawing.
A note about Peter Lewis' terrific article. No one knows more about the archival materials related to the Old Course than Peter. One of his research projects over the last several years has been to find and present evidence of the architectural evolution of the Old Course pre-1900.
Unlike the post 1900 era, there were many major changes to TOC in the 18th and 19th centuries. The course went from 22 to 18 holes, the current 18th green (previously the 22nd green) was probably located at one time under what is now the Old Tom Morris Shop, the course was expanded to the east to create the modern outward nine, double greens were built, others were rebuilt, bunkers were removed and added, etc.
The historical record of those changes is, however, very limited. Beyond generic references to changes by Robertson and Morris in the middle and late 19th century (many greens doubled, course width expanded), there are no documents giving the rationales for or the details of their changes. There is even less material about earlier changes.
That includes the change that took TOC from a 22 hole to an 18 hole course. The first several and last several holes of TOC were the holes most affected. Who directed those changes remains a complete mystery. Which, I think, makes for the single biggest unanswered question in the history of golf architecture. Those holes are today among the best in the world, yet we have no idea who designed them. (Looking forward, what will happen to those holes under the current Dawson administration is anyone's guess. Based on his actions to date, Dawson seems to have no qualms about making any changes that strike his fancy.)
So Peter Lewis' article on the 1754 picture, painted a decade or so before TOC was reduced to 18 holes, is an attempt to fill in one piece of what is a largely missing historical record pre-1900. I hope Peter will continue with his project and perhaps someday compile his findings in a book. He is on a fascinating hunt.
