The date of manufacture is stamped in the neck of the tank.
Ok...you have a point. And I knew that!

So the sticker that the tank comes with with the date hole punched in it is like a backup...It's redundant. I must have bought a DIR tank...

ANYHOW. So nobody thinks the tanks, having been sealed up and esentially dry since assembly and sitting for a month, should have any issues with them physically?
