I need help identifying the 1st and 2nd stage oceanic regulator on the attached pictures. They were bought new between 1995 and 1997. The 2nd stage is blue and says Delta but dont know if it is the Delta or Delta 2. The 1st stage has no marking other than a serial number. Any help identifying the model number as well as the Oceanic replacement part kits that go with it would be great! Thanks everyone!
