**The picture "ACSC (AGA) testduik" is taken on the marine base "Skredsvik" on the Swedish west coast. looking on the cars it is likely to be in the late 1970's Also, the guy in the black Unisuit is mr Imre Botos who is still the marketing responsible for the Interspiro diving products... He was one of the test divers when the ACSC was developed.
