I have two Sea-Vue SPGs made by Sportsways. One sports a Huntington Park, CA address, whereas the other says Los Angeles. Does anyone know when these gauges were made, and/or when Sportsways made the move? To complicate things, I guess that Sportsways was in Paramount, CA in 1963 according to "Basic SCUBA".
Also, during what years was Selpac in business?
