These were 3000 psi steel tanks from the late 80's to early 90's. The 6" diameter was the give away. 25-26" tall.

I think the OP really wants the 6" diameter.
Faber made two 3AA 6" diameter 3000 psi tanks:
1) 464 cubic inches internal volume, 6" diameter, 22.05" tall, 3000 psi) weight = 23 pounds, buoyancy = -7.1 pounds full, - 2.5 pounds empty. This tank held 60.2 cu ft at a plus rated 3,300 psi.
2) 550 cubic inches internal volume, 6" diameter, 25.39" tall, 3000 psi, weight = 26 pounds, buoyancy = -7.6 pounds full, - 2.3 pounds empty. This tank held 71.4 cu ft at a plus rated 3,300 psi.
Tank number 2 is what the OP wants and it was marketed by Scubapro for several years.
A pair of them would make superb sidemount tanks. I doubt you could get the 150% overfill you can get in cave country with 2400 psi tanks (4500 psi versus 3600 psi) but at 3600 psi they'd hold 78 cu ft, and at 4000 psi they'd hold 87 cu ft.

DA, bingo on all fronts! SM and yes, slim 72s.
Couple leads, but all in play.

Derrick, excellent find!
I have a set of the shorties and a set of the slimlines now.
Alas, neither work well as SM tanks. Way too negative… Maybe with 10/70 in them for saltwater at some point.
I’ll be rigging the Slims as doubles or onboard bailout on my RB similar to the GUE style LP50s.
