My 72 steel has a born date of 1964, and passed hydro last year. I know there are guys with even older ones.
How about a 1800 psi steel 38 from 1943.... I need to get it hydro'd. It's still current till December, but the vis just expired so I might as well line them back up.

I dive with a guy that has LP72s of that age that still have their "+" rating

Tank life is complicated. I have tested cylinders dated back to 1908 with so many hydro stamps I had to erase some to affix the new one. Not SCUBA of course but as long as not over-stressed due to over filling they can last a looong time. The safety factor is huge. I don't think Al cylinders will last that long.
