Mistral

The direct successor of the CG45 appears in 1955, several versions have been made.

Model Date
CG45 1946
Narghile 1956
Mistral Avril 1955
Aquamatic Avril 1958
Calypso Mai 1962
Aquadiv Mai 1962
Royal Mistral 1963

Most of the datation above is based on the adverts from the magazines l’Aventure Sous-Marine

In the number 19 of l’Aventure Sous-Marine (jan 1959), La Spirotechnique advertised that they have sold more than 100.000 Aqualung « Cousteau Gagnan ».

In the number 37 (mar 1962) more than 200.000 Aqualung «Cousteau Gagnan » have been sold.

In order to be able to date the regulators, three changes of address :


Brand new Mistral
