I looked up some 1965 listings just now and see 703-SO5 (765) appearing at Fort Belvoir and Mount Vernon. Notes made much later which I have seen say that 765 is an Alexandria exchange in the Groveton area, which is the next exchange down U.S. 1 and the Potomac River from old-town Alexandria. Fort Belvoir and Mount Vernon have since split off from the Groveton ex- change, and a new exchange area, south of the now-reduced Groveton exchange area, was set up. I know that 360 and 780 serve the Mount Vernon area, with some 781 (Engleside, the next exchange to the south, and which is toll to Md.) mixed in; 664 is at Fort Belvoir, and I don't know what is on the pay phones at Fort Belvoir.
