It is a steel tank (DOT 3AA). Working pressure is 2250. 253364 is its serial number. ^71 is probably its first hydro test. It was probably manufactured in 1970/71.
It needs to be professionally inspected and hydro'd before used.

Sounds like you have an old steel 72cf cylinder. The '+' symbol means it might be rated for a 10% overfill. Have your LDS check it out with a hydro and viz. If it passes you'll have a nice cylinder that'll last forever. I have two identical 72s and they're great for recreational diving(one is almost 40 yo). You'll take some weight off your belt as well.

You may want to wire those up in a doubles configuration.......
re: 72s, the "+" is the orginal stamping for a 10% overfill, but a lot of folks, including dive shop monkeys don't know the reason it came about.... http://diverlink.com/downloads/gear/tankfills.pdf
