The 6/31 I believe to be the mfg. date.
On the left tube there is a small crown above a 6 beside the eagle. On the right tube there is a faint eagle; possible the crown and 6 didn't take. The faint eagle is about a third inch in front of the 6/31.

There also appears to be crowns over the U on the flats.
