Ken, what is the TC stamp on it? That's the Transport Canada marking. My E7-120s show Tc SU-4349-230 PST.
Not exactly sure what that means, but to help you decipher a bit of it....
The TC3AA is probably a low pressure steel classification. The REE stands for rejection elastic expansion, if exceeded during a hydro test will be rejected. As for the rest, you got me.

It sounds like you have a PST 104.
Which is basically the same cylinder as the E8 130.
The E series cylinder's have been re-rated, the old HP's are now rated for 3442 psi and the old LP's are rated for 3442 psi.
Pst does not make HP130's, all of the E series cylinders are rated to 3442 psi, the difference between the E7's and E8's ias the diameter of the cylinder, E7=7.25" E8=8.0".
DOT-3AA2400 3-00+
Dot=Division of Transportation
2400 is the working pressure
3-00+ is the hydro date, the + means it was tested for a 10% overfill, so the working pressure is 2640 psi.
Only PST makes the 104, OMS and Faber never did.
The 104's are nice cylinders, I am sure you will be happy with it.

Keeping it as a singles tank is probably your best option. A set of double 120's is a real gut buster and you will rarely find a use for it.
I bought two 112s with the idea of maybe doubling them if needed. I've determined I'll never do that and would get a pair of the new E8-130s if I had it to do over. They would be good as singles tanks and doubling would be viable if needed.
In the meantime, the 112s are a good match with a drysuit and are good with a wetsuit under some conditions. They are pretty much useless for diving with no exposure protection in fresh water.
TC - 3AAM184
31A00 REE 87.9
81
Ken, that 184 is the service pressure of the tank in bar. 184 bar x 14.7 psi/bar = 2700 psi.

A 'BAR' is not exactly one atm. It's a scientific numeric equivalent to approx 14.5 lbs/sq in. Thus, 184 bar = 2668 psi. I mention this to prevent scientific drift on the vaunted SCUBA Board.
Sorry, I stand corrected. It was more of an estimate I can easily do in my head.
Thanks.
Thanks.
