Wow, that second stage diaphragm uses the same design principal as the old US Divers (now Aqua Lung) Aqua-matic (from around 1957). The same wedge effect sliding between the levers.
It was the first single hose from US Divers/ Aqua Lung.
Interesting, yes, looks like the same valve type.
The first Baramat came on the market between '70 and '73, so quite some years after the Aquamatic.
Barakuda started selling Aqualung Regulators in their catalogues in '66, so probably they cut a deal with AL in the early 70ties that they could produce their own Aquamatic 2nd stage version.
The 1st stage seems to be a German design, the 2001 and 2002 (not the Baramat 2000) have been remarkable in that sense, that they were some of the first 'dry' Piston1st stages on the market. The ambient pressure was transmitted via a rubber cap and three metal pins, similar to the Cressi and Beuchat wet designs.
Unfortunately did in the beginning quite some caps come off when diving, so those models gained (as others) a reputation as 'widow makers'.
In Germany Barakuda sold a lot of their Baramat regulators, although they were considered as hard breathers. No wonder, if the technique was from the 50ties.
Still interesting pieces of Vintage Regs.......
