Today I got a 2.5lb CO2 tank off Craigslist for $10. The guy found a couple of old regulators and gave them to me, he didn't know if they still worked or not. I figured I could clean em up and use them. I've never heard of these brands, so I don't know anything about them.
The blue one is a Norgren and the other one is a Cornelius. Are these single or dual stage, and if I cleaned them up, possibly replaced the gauges, could I use them? If so, which one is nicer?
I assume that I'd need a CGA-320 fitting for the Cornelius reg.
Any input would help! Thanks!

Thanks for the input guys! I looked into these regulators more, and they're both commonly used for kegging. The cornelius one is a dual body, so it has dual outputs that you can set to different PSIs (if you wanna tap two beers at different PSI). So I guess that one is ruled out for now (until I decide to use one tank for two aquariums).
The Norgren one is single stage, unfortunately (and yes Darkblade, you're right about the pressure release valve - at first I thought it was a knob of some sort). This one has a cracked gauge cover. Once I get the tank filled I may test them out, but I don't think I'll use them for the time being. I don't need the dual body yet, and the Norgren is pretty beat up. Maybe I can pawn them off to a homebrewing friend haha
