The Chevy Chase Club, Chevy Chase, MD. This is from a history of the club through 1957 that I found at a used bookstore. (I did not take it home with me, as there were only about 10 pages on golf and I haven't played the course.)
The course's original 9 holes are diagrammed very faintly with white dotted lines on the east (bottom) half of the property. The original 18 hole course is diagrammed with the darker lines and hole numbers. Finally, the 1922 Colt/Alison course, as it appeared in 1957, is portrayed in the background with green numbers.
If anyone is interested in clarification on the routing of the original 9, I am happy to provide it.
