    I recently came across some old tanks and at a price I could pass on. I realize it was a risk but pretty low so went for it. One was condemned and xxxx out. One looks like. 46 or something with a 1/2 valve? One has similar threads and a bottom that looks like a plastic coke bottle. I’m left with 2 72’s that may be of value (assuming the others are not, feel free to correct me). I got the valve off of one of the tanks, inside looks decent (at least worth taking it in) it has what look like normal threads to me, but a conical void at the top of the neck that has a gasket or something. Will this require a special valve? Will a new valve and standard o-ring work.
    The other looks to have 1/2 threads, can these valves can be found ? Can I get one with DIN?

    As always thanks in advance for the knowledge that will be shared.

    $75 on Amazon. Not great but not a deal breaker

    I’m not sure which it is. I just got the valve off no Teflon tape, but also no o-ring on the neck. How can I check ?
