Need help identifying this tank.

[mksmith713]

I have a tank here that has the following markings.

DOT3AA 2015

337 826 D (below the 337 is the letter "M" and below the 826 appears to be a "C")

3 98 12 06

SPUN 10-83 (beside the 3 98,12 06 and 10-83 there is a + and a star)

Would like to know if this can be used as pony bottle
I think it's a 25 LP

Thanks for any help in advance.

The DOT3AA 2015 would make it a steel tank with a 2015 psi service pressure and the plusses after the hydro test dates indicate it has been approved for a 10% overfill to 2216 psi on each of those occassions. The + after the 12-06 date is what counts.

As long as it accepts a 3/4" scuba valve and is suitably sized, it should work fine for a pony.
