They are aluminum 80s. What you will need to do now is get them Hydroed and VIPed. First what I would do if I were you is drain them and look inside with a light. If they look clean and there are now visable cracks then stick your finger in and feel the threads for cracks. If it all looks and feels good take it in to get Hydroed and VIPed. You are looking at 40 and up for then Hydro and VIP. You will need a visual eddy done on the threads when you send it to Hydro to check the strenght of the threads. If it all passes you got yourself a great deal.

Please read the thread. The OP has already hydroed them. AL80s from 1991 do not require visual eddy testing.

I would like to add you can buy "air" on the WWW, but you are not buying the actual air because that is free, you sitting or standing in air. You are buying the method to compress air from 1 atmosphere (14.7 psi at sea leve) to 4,000 - 6,000 psig.
