Want to post images of rest of the neck? Diameter?
 
What do you want to know?

It is a steel 3AA LP cylinder 2400 psi made by PST in June (6) 1996. It has a plus rating so it is full at 2640 psi. About all I can not tell is the capacity. Need to have some measurements of the cylinder.

It had a plus rating but current hydro (5/20) doesn't have a + so now iit's 2400 psi max.
 
If the REE is stamped on the cylinder, it should be a simple matter of asking the re-tester why it did not get the + stamp. They should have kept the data so having the stamp applied might easy.

The REE might also be found on the attached document.

I love when people present a poor scan of a 52 year old document to me so they can get a plus rating on an old tank. Especially when it is a steel 72, and that line has a misprint on the pressure rating.

Correct but that does not change the fact that it is "full" at 2640 psi.

A few years back I took that document to a hydro tester. They were happy to have it and used it immediately to plus rate some cylinders.

It's full when it is filled to working pressure; which in this case is 2400 psi. The nominal capacity is at the 10 percent overfill pressure but that's just marketing.

They can do whatever they want. Risking their RIN to apply an arbitrary stamp to an old scuba tank based on a misprinted scan seems a bit foolish.
