USSR COLD WAR ARMY NAVY 50 METER. NEW & COMPLETE IN ORIGINAL CONTAINER. I personally bought this depth gauge in a Moscow sporting goods store in 1990. After the fall of the Soviet Union, many military items “found their way” into the civilian sporting good stores. This one is dated 1973 and is serial number 866. It has never been used and comes with the original wrist strap, plastic case and paper documents.
