NRL was one of my favorite customers in the early sixties when I sold for Tektronix in the D.C. area. Very fine group of dedicated people on all levels. Competent, courteous, and capable. The massive sewerage treatment plant joining NRL to the south, put out significant sulfurous fumes which reacted with the silver solder on the then ceramic mounting strips we used. This reaction resulted in silver migration resulting in significant damage to the instruments we built. When I left that area they were going all out trying to solve the mystery of the Thresher submarine incident.
