    I have 2 sets from 1990. They were for my wife. Very easy to handle and fit a jacket BCD.
    I dove them many of times. You don’t know they’re on your back

    Same as you would with a typical cylinder.
    Loosen the strap so it’s long enough.
    There is a rubber spacer that fits between the tanks to keep the spacing.
    If you’d like, tomorrow I’ll take a pic and post it

    Please Check page 8 of the 1988 US Divers ( aka Aqua Lung} SCUBA catalog
    (2020-1988 = 32 years - not real old - but old....

    You have two cylinders and the K valve from a 1988 US divers ABS system
    ABS = Advanced Breathing System
    (Not a "UDS System" as previously posted )
    Produced when J M Cousteau had some influence at US Divers

    90 coft @ 3000 PS

    Contained in a plastic shroud

    Marketed as
    Part # 2900- 00 Sliver color
    Part # 2900- 10 Blue color

    Sold with an inflatable "alpine style " ( ?) inflatable back pack

    Individually as components = ie K valve or tanks are and will be considered rare collectable and have considerable historical significance and value to a collector or current user of the ABS system.

    The units as pictured appear to be almost pristine with adds to its collection value .

    It was a great "Yard sale" purchase for $5.00 -- worth many times more that $5.00

    Very good for @agadiver78 '

    who according to his avatar
    * has never dove
    ^ Is not certified
    * provides no information as to location where he resides

    Yet he freely dispenses advice...

    Sam - Explain 90cu ft at 3000psi. Are you talking about the OP's double 30s?

    I see two Al30 cylinders rated for 3000psi usage. I'm perplexed?

    Tanks were available in single, double and triple configuration
    Single with a K valve.
    Doubles with a manifold as you’ve seen in the OPs original like post.
    Triple tanks with a manifold designed for 3 tanks. I’m sure there’s a pic somewhere on this site.
