A 72 is 65 cf at 2250 psi,so they would be less than that. I would keep them as doubles.

Up load a photo on here and post that you have them on Vintage Double Hose. Those steels should have a lot of years left in them as long as they don't have a lot of pitting. If they have the 3/4" valve thread they should be more desirable then the pipe thread tanks.

If you are not into the vintage era, then sell them and use the funds to get yourself a good set of more modern doubles if that is the way you want to go.

That could be a set of 1970's 72's, some post 1990 aluminum 80's, LP 85's, or 100's.

There are plenty for sale on this web site or on the Deco Stop. Also check craigs list and your local dive shops to see if they have any sets for sale.
