Knowing a bit of the history of this tank, I KNEW it was welding

This narrows it down to either oxygen, fuel, or sheilding gas for
welding, or CO2 for beverage carbonation.. Knew it wasn't Oxygen - as
O2 bottles have LH threads.
No smell means not Acetelene, and not propane or MAPP.
That leaves shielding gas or CO2, Argon, Helium, or a mix.
My voice didn't get squeaky, so it's likely not helium, and none of
the others are dangerous in small quantities.

I'm pretty sure it was CO2 - and being as far out of date as the
hydro-test appears to be on it, it will likely end up in the scrap
bin.

Don't be too sure - As long as it isn't rusty, or wasn't dropped too
many times, it's worth a try. Or just turn it in as a straight
exchange and let them worry about the hydro. I bought an original
military 2.5# CO2 extinguisher that was last tested... Let me go grab
it.

(Gee, guess it's a bit overdue again...)

The guys at Pioneer Fire were going "Military, Spun tank, that'll
fail." "It's passed before, give it a try." Passed with flying
colors (hence the 4P85 recert and refill) - popped off the belly band,
painted it red, put the belly band back on, and put it on my matching
vintage generator.

I've seen a LOT of "antique" bottles in daily use - go look at the
first entry on the long list of recert dates on some of the ones out
in the bins, and you'll get a surprise.
