I worked in a tank farm and were required to notify the Coast Guard whenever there was an oil spill in the water. Tanker had dumped their scrubbers into the east river in NYC. Since the regulations begin with "causing a sheen or discoloration in the navigable waters". They got notified,and we put out booms to contain the spill. Coast Guard shows up and has a 45 auto in a holster so we show them the ship with the boom deployed and they go on board to question the captain. Well we took samples and some were given to the CG on their boat. Anyway started talking to one of the CG sailors about his 45. Told him that the pistol he was carrying was older than he was. Since the gov't stopped getting them shortly after WWII. Sure probably more were made for Korea but just likely they were overhauled or rebuilt. Frank
