Old acetelyne tank

[Big Barn]

Any welding shop that has been in business for a few years should be able to answer your question. might even find a used adapter

Both of the two LWS I deal with (not mom and poppers) couldn’t help me. Just depends on the staff/management.

Most likely a branch that does actual filling on site would be more knowledgeable.

Other than right hand threaded B and MC fittngs there was also one called POL. I think that's what you may have here. In any event that is an old old cylinder. I'd check it close for rust weakness or take it in for a pro inspection. The Railroad had their own acetylene fittings as well. Simply called Rail Road. Even had their own rail road size fittings on the hoses.

A POL is a CGA 510...And POL is a bastardization of "Put On Left" which original came out the 1880's when carriages and first motor cars used acetylene lamps for head lamps and it was "Prest-O-Lite"....

The CGA 510 (POL) is also same "connector" as on propane tanks (not acme screw thread ones)...

Ok, There is another one then. Haven't had a Western or Superior book in my hands for years. Might have been "Commercial" CGA.

Just checked my stash. Here’s a CGA 510 Dale mentioned coupled to a CGA 520.

I think there may be “military” gas tank fittings also?

On further research tank valve may be CGA 300....

"Feels full" is kind of a misleading statement since those bottles are always full. The are full of a substance that looks similar to concrete and is very porus. The acetone and acetylene gas are suspended in that substance in the bottle. Therefore weighing the bottle without knowing what it weighs empty is kind of a wasted effort..............................................

The company I used to deal with had that type of valve ,and I had to use a Forney 87799 CGA300 to CGA 510 adapter

You might want to find out if you're going to able to swap this tank out for a full one or get it filled before you expend too much energy and money on it. It probably needs tested before another refill. I suppose if it's actually full it would be worth an adapter.
