    Scroll down to see Spiro Supra XL 1987. First stage looks like a match?

    The made in France stamp on the yoke and yoke screw looking like US Divers/Aqualung helped with the search.

    A bit of trivia from the website...
    "In 1998, probably after the death of Commander Cousteau's Aqualung brand decided to put all the products manufactured by LA SPIROTECHNIQUE, US DIVERS, TECHNISUB and SEA QUEST under the same name, AQUALUNG"

    Thank you, Kupu.

    What caught my eye was the redundancy, having the same outlets on each side.

    Two HP's and four MP's total. What were they thinking of building a first-stage like this?

    It was like two first-stages built into a single-stage regulator.

    On the other side of the yoke is stamped 3000psi.

    Maybe is indeed a "twin regulator", one body for two first stages.
    Here is a modern version:

    Interesting. It looks like the cousin of my circa 1991 XL model.

    I still use it, although piston replacement parts are almost obsolete. I would like to find a DIN conversion for it.....

    So that is what happened to the second generation Seapro twin first stage from the late 80's.

    That reg was marketed in the US as the 1st Generation US Divers SEA that first appeared in their 1988 catalog. In 1989, the body was redesigned to what they used for many years thereafter.
