The born on date should be stamped on the tank and yes that is a jvalve.
Look around the top of the tank, you will see several sets of numbers and letters. One will contain 3AA or 3AL, the AA is a steel tank, the AL is aluminum. Next look for 1 or 2 numbers, a special character followed by 2 more numbers something like 2$68 . The 2 is the month, in the example Feb, the $ is a special mark (brand if you will) of the hydro facility and the last 2 numbers are the year, 1968 in the example.
As for the valve, yes that is a J valve and as long as you understand it's operation there is no good reason not to use it, reguardles of the BS some will tell you. Assuming its operating properly.

This link might help:
Crown Markings of a SCUBA Cylinder
That said it appears to at least be mfg from Al.
And if made by Luxfer before 1990 read this sticky link:
Is my cylinder made from the "bad" alloy aka AL6351?
