Sounds like Cornelius kegs. They are not that cheap anymore as they are
popular for serving homebrew and the supply of surplus ones have dried
up. You can also get new ones, some are very similar to the original
ones and some are made from thicker SS.

They're used behind the counter to feed soft drink constituents into a drink dispenser, maybe still in use today.
8" diameter about 2' long, 5-6 gallons with a quick removal top oval fill port on top with 1 or 2 QD pressure connections.
They were sold as SS scrap at the local scrap metal yard in the west bay area near Redwood City at $5 a pop, no pun..

Interesting, how did it end up there?
I built that as a personal project to fly a bi-prop late/early
70's/80's, using SS 7UP beverage containers but before fruition I
got immersed in Bob's project(s) in which he needed a test article
that the 7UP rocket was ideally suited for,i.e. underwater
ignition of a LOx/RP rocket engine. I may have mentioned the web
site: <neverworld.net <http://neverworld.net>> which has videos of
these and many other videos and info about Bob's projects
including SEALAR,Sea Dragon,etc.
FYI, I bought the 7UP containers for $5 each and hydro'd to 900
psi before finally giving up due to fatigue as I was using a
surplus hand hydraulic pump. The walls started to yield at 600 psi
and gradually work hardened when I ceased pumping at said
pressure. Probably would of failed ~1KSI. Amazing little
vessels,still use a few for Jet-A storage.
LOx of fun. Good night my friend,

Yeah Rick, I can help you being as comfortable working with
LOx as am with kerosene or water, well over 50 years of experience
including the LR-101 Vernier rocket engine in which there are
some YouTube videos of a few of my firings from the 70's.
Much to discuss so probably best to talk of list.

Hi
Has anyone on the list used Swagelok compression fittings
in service with LOX (3/4 or 1 in)? I’ve used AN (37 deg
flare) and NPT fittings successfully for LOX. NPT fittings
are wrapped with PTFE tape. My entire LOX side on my test
stand is all AN expect for the NPT adapters used on the
main LOX valve and LOX load valve. Any LOX experience
with any other brand of compression fittings (Parker,
etc). I’m looking at changing the stand plumbing and am
considering Swagelok. Check out our Facebook page
https://www.facebook.com/midwestpropulsiongroup to see the
stand in action.
The Army missile spec forbids NPT fittings. Most likely
reason is they could vibrate loose. I’ve seem amateur
liquid systems using NPT fittings successfully. Any
advice would be appreciated. On my first test stand, I
welded the NPT fittings together. It worked but looked
pretty bad. An A&P I know suggested safety wiring the
NPTs so they would come loose. That is a lot of work.
I’m lucky. My outbuilding is also my rocket workshop.
When I want to escape I run out back for a few hours.
Thanks and everyone take care.
Be Safe,
