Double 30s???

[in too deep]

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

How do you strap them onto a jacket bcd?

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

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.

the triple setup had a weird bent v manifold also
