Here is one of the most beautiful pieces in my collection: a mistral 6 RUE COGNACQ JAY PARIS VII numbered 217, (the smallest serial number I know).
It belonged to the right arm of Bob Denard (former mercenary of the French government who operated in black Africa in the 80s) and this diver would have even used it to make red coral at more than 100m in the air.
It is equipped with the very rare GODEL mouthpiece with snorkel from 1955. It is a MISTRAL of military origin.
Another MISTRAL 6 RUE COGNACQ JAY PARIS VII, this one with the particularity that its serial number 1394 ends with the letter A. It probably has a professional origin but that remains a hypothesis because nothing allows to affirm it from our days.
Another very nice piece from my collection, a new MISTRAL 56 numbered 2901 and mounted with a PRO tip. I called it that because this variant was only produced in 1956. It differs from 6 RUE COGNACQ JAY only by the address of the label which becomes 27 RUE TRÉBOIS LEVALLOIS (Seine).
Here is a MISTRAL 57 numbered 5611. It is one of the very first cases now closed by a rod. The staples will only be used for professional hookah regulators. Inside the HP seat in the body is now removable while that of the 1955 and 1956 units were machined in the body.
Above another very rare piece from my collection, a new MISTRAL 61 or SUPER MISTRAL. It has the serial number 10233. It is the "big brother of the ROYAL MISTRAL".
The MISTRAL in its latest evolution with the AQUASTOP second generation mouthpiece, it will be marketed with the address 27 RUE TRÉBOIS LEVALLOIS (Seine) from 1962 to 1967. This one carries the serial number 20872 and I estimate its year of marketing to 1965. It is new.
My favorite regulator numbered 9221 with which I dive regularly. It was my first acquisition in 1994. Purchased second-hand in Annecy in the shop of the late "Fanfan" Baudrion, It belonged to a former gendarme. It is probably an old MISTRAL 61 to which the first generation AQUASTOP mouthpiece has been replaced by a second.
Here is a MISTRAL PRO in stirrup, that is to say that it is mounted with a front saucepan from NARGHILÉ MISTRAL from 1956 and a rear saucepan from NARGUILÉ 1965. This version has never existed to my knowledge in the catalog of La Spirotechnique . It is probably a montage made by a professional diver after 1965.
A military version of the MISTRAL with the address 27 RUE TRÉBOIS LEVALLOIS 92. It is reformed from the French Navy, checked on 05/24/1977 and it is new! never saw the water! It carries the serial number 27531 and dates from 1968. It is mounted with a new GODEL mouthpiece which is extremely rare because the rubber of this tip is of very poor quality and the majority of what we find in our time are cracked and dried.
Here is another reformed MISTRAL Navy regulator which belonged to a former member of the Hubert commando. . It is new, has never seen water, it also has a revision date engraved on the bowl of 08/16/1987. It carries the address 114 RUE MARIUS AUFAN 92 numbered 39281 and date of 1977. It is therefore one of the last MISTRAL marketed and it seems that this last series and was sold to the Navy because I found other MISTRAL with a serial number around 39000 all reformed Marine Nationale.
Another MISTRAL Marine Nationale reformed which was on Forbin, this one carries the address 27 RUE TRÉBOIS LEVALLOIS 92 numbered 32280 is probably dated 1969/70. Like most MILITARY MISTRALs it has a GODEL tip.
Here is this beautiful military MISTRAL painted black with a GODEL tip. A priori this model was used as training for the soldier of the Hubert commando, impossible to know its date because not numbered but probably between 1965 and 1975.
To finish my MISTRAL collection, here is this magnificent MISTRAL from the Cousteau team with a DIN 300 bar assembly designed for the use of titanium quad-bottle diving suits. It was given to me by a former member of the Calypso crew who embarked on expeditions for 27 years. He told me that these ultralight diving suits of the latest COUSTEAU generation (rediscovering the world) were abandoned around 1986/87 because one of these exploded bottles aboard the Calypso, fortunately without death or injury because the incident occurred at 11 p.m. when he was on shift.
