Western European Two Hose Regulators

Swiss made "Colombomatic" Colombo two hose regulator, probably from the 1970's.

Super Sealion
Submarine Products Super Sealion, made in England. This was a single stage regulator from the early to mid 1960's.

1960's Dive-Safe Loosco two hose regulator. I believe the Looscos were made from the late 1950's through the early 1970's. The earliest models had a curved metal mouthpiece, and later ones used the La Spirotechnique Aquastop rubber mouthpiece. I'm not sure if this example has the correct mouthpiece or not. Early models mounted to a tank with a "B" nut, but later models had both DIN and international fittings.

Early 1950's Siebe Gorman Essgee MK I, made in England. I believe this was the first model SCUBA regulator sold by Siebe Gorman. It is two stage, and has parts almost identical to the early Spirotechnique CG-45 and early US Diver's "Trademark" Aqualung. The hose assembly is not original to this regulator, but I believe it is similar to the original. Note that someone welded a "wing-nut" to the original yoke screw.

Siebe Gorman "EssGee" Mistral. This single stage regulator was made in England around 1962. Production costs must have been very high with the complicated threaded elbows.

Heinke London
Heinke London, Venturi Jet, Made in England. Probably dates to the early 1960's.

Original La Spirotechnique CG45 (Cousteau-Gagnan 1945), with a serial number in the mid 600's. This rarely seen regulator probably dates to about 1946 or 1947. The rubber mouthpiece is original to the regulator, and I am looking for original hoses. This model is the first production SCUBA regulator ever made.

Spiro Mistral
Mistral made in France by La Spirotechnique, the first diving company to sell Jacques Cousteau's patented "AquaLung". It is single stage, and almost identical internally to the US Divers Mistral. Circa 1960's.

Royal Mistral
La Spirotechnique Royal Mistral, with Aqua-Stop mouthpiece. I am not sure how this differs from the original Mistral, other than the redesigned case.

"Champion" two hose single stage regulator, made in France by Cavalero & Cie. Probably from the early 1970's. If the mouthpiece is original on this example, it is the same as the one used on the British Submarine Products Super Sealion shown above. The "Champion" is a very rare regulator and details are scarce.

La Spirotechnique of France allowed an Italian company to manufacture Mistrals in Italy. This is a fine example of the Spiro Sub. Notice the unique yellow plastic mouthpiece tee. Circa early 1960's.

Salvas Aquasprint two hose regulator with factory face mask. Made in Rome, Italy, probably from 1952-54.

West German Drager PA 61. This is a two stage regulator from the early 1960's. It is a high quality and good looking regulator with blue hoses and mouthpiece, yellow hose clamps, and quick release fittings on the mouthpiece. This model still has the lead seals from the factory that seal the body clamp screws. It is interesting how the hoses have darkened with age, yet the mouthpiece is still a bright blue.

Nemrod V2
Nemrod V2
This is the first model of the Spanish Nemrod two hose regulator, called the V2. It was introduced in the late 1950's. Soon after, the name was changed to "Snark III". The Snark III regulators were sold in North America beginning in 1959, distributed by "Seamless". Production continued until 1998, giving it the distinction of having the longest production run of any two hose regulator.
