Old doubles rig

[JahJahwarrior]

Kirk, you have your answer. These pre-1990 aluminum tanks are probably OK but there will be an expense and general hassle factor when attempting to use them. The dive shops may be reluctant to deal with them. The required visual inspections require special equipment and will be too expensive to justify ownership. The actual value of an old aluminum tank is about $50 on EBay but shipping and other expenses would raise the cost of ownership and a knowledgable person probably would not bid.

there are lots of idiots. You can watch tanks older than these go for 60 with 40 shipping all the time, even though you can get a new AL80 for like $140 shipped.
