mikey3091 - If these tanks are pre 1990, I doubt I would accept them if they were free, forget about paying for them. I have two pre 1990 aluminum tanks that local hydro shops will not hydro anymore. Check the DOT site, there is a warning on T6351 tanks. DOT will provide the batch numbers of the tanks involved. Some shops are using this warning to refuse to fill tanks made from T6351. If these tanks are made from T6351, they may be useless to you. I think this web site might shed some more light. 3AL CYLINDERS.
There are several threads on this topic.
As others stated before, buying an old tank, spending the money for hydro and such may cause to spend near buying a new tank. Your call. Spend the money on a new tank or buy something 20 years old? How much longer will it be usable? If the tank is good, how long will the valve last? To me, not worth the exposure.
Sorry to leave such a bleak impression. I got burnt, would hate to see others take a similar beating. Tom
