How many are there; four?
One is a steel, 1800psi, born Jan 1976, latest hydro maybe Jan 1991.
One is a steel, 2250psi, born Jan 1967, latest hydro maybe Jan 1975.
The two that show Los Angeles on them, is this the back of the first tow tanks, or two additional tanks? If this is two more tanks, you need to show a picture of the other side of the tanks. Both of them may have a 2001 latest hydro, can't really tell.
None of them are fillable as is, they need to be hydro'ed.
And chances are good they will need to be tumbled.
They all appear to have PSI stickers on them; what is the date of the punch marks?

There a total of 4 tanks. 3 are the longer skinner kind one the shorter fatter. Last VIS was 01, hydro stamps all over them some dating back to 67, may be a question for the vintage diving form. I was able to make out the fill pressures from the stamping but not the capacity, which is what I'm really trying to figure out. Manufacture would also be nice. If they pass hydro even with a tumble and new valves I think I may have not made a bad gamble depending on their capacity. The online tank charts I can find don't have anything with those fill pressures.

the one born in 6/67 that is image #5 is made by norris. You're not going to see these on online charts because they are vintage steels, so you have to go off of some other information, but posting pictures of the tanks from afar does nothing for ID. You have to post all of the markings on all of the tanks, and then we might be able to help you
The smaller tank is probably a PST 50. The were marked at 1800 psi and held about 47 cu ft unless filled 10%.

The photo's order got mixed up loading. The far shots were meant to show what tank the marking belonged to. I have included all the markings they were in the tanks. I did not include the many hydro re-qualification stamps. Seems like I got 3 old 72's and a big ass 50. If they look decent in the inside I may get the 72's in Hydro as I think they could make nice tanks if I get into a side mount rig or as a doubles rig. I can't really think of what the 50 would be good for
