Craig,
I have 2 sets of drawings for the Army-Navy Country Club in Arlington, Virginia. The earliest one is an incomplete routing map dated May 1948 and shows JBMcGovern's proposal for the relocation of the 15th hole due to the relocation of South Glebe Road as well as its intersection with S. Army-Navy Drive. There were 27 holes depicted on this tight and undulating property. The redesign called for moving the 16th tee, the 26th tee, and the 23rd green.
I also have a routing map of all 27 holes on the Arlington site by William Gordon in 1949. It would appear that he proposed changes to the 1st, 3rd, 4th, 6th, 9th, 13th, 15th, 16th, and 17th holes as these are shown in detail while the other 18 holes are stick routed. Old Camp Road and Old Georgetown Road are shown at the top of the map. There are no compass points indicated. Using the McGovern map it would appear that those roads are on the south side of the property.
If you like, you can email me the aerial and I can take a look and see if either proposal was implemented.
