Things to consider when choosing a used tank:
how old is the tank?
*while steel tanks are okay Walter Kidde, US Divers and Luxfer aluminum tanks from 72 to 89 have been removed by the department of transportation due to the poor quality of the aluminum alloy that was produced back then.
when was the last hydro?
*If it's way out of hydro you are taking a BIG risk
when was the last vip?
*If it hasn't been VIP in awhile you are taking a BIG risk
if it's completely drained of air when was the last time it was filled?
*pitting, rusting, and other things occur when stored without air for long periods of time. Always, always keep some air in your tank.
how was the tank stored?
Steel tanks rust easily if not taken care of.
The main concern is what the tank looks like in the inside. While the outside (based on the pictures) doesn't look like it would fail the inside is a different story. If it still has a 50-100 psi in the tank still I don't see a huge problem with this tank. There may be some pitting on the bottom of the tank but I can't tell from the pictures. If you think this tank is worth a potential investment of $80 then go for it.

If they won't fill it strickly because of it's age and material of construction even if it passes hyro and vis it is useless to the diver and is in fact defacto condemed.
Yup, we sold our scrap (grade 2) yesterday ... $100.00/ ton ($0.05 cents per lb.) I can't imagine why someone would pay $1.00 per lb. for scrap steel. That's well more than virgin mat'l costs.
Is the tank in the OP vinyl coated or painted? Any galvanizing under the paint to vinyl? Or is it bare steel under there? If bare steel I would avoid this tank, too much work to check under that broken coating for hidden pits and then you'll need to re-cold galvanize it.
Only with the owner's consent. You should get that in writing. Only hydrostatic testing carries any federal legal consequences. There are of course, many slippery civil slopes in visual inspection.
