H J,
Congratulations!
Your TSMG is just a few thousand above mine. Looking at your serial number and model stamps, first it was an M1, then you will notice the "A" and the "1" are not the same as the "M1" as they were added when the gun was first made, and finally (as noted above) it was "XX'd" back to an M1 with the use of an M1 bolt.
FWIW, mine stayed an M1 with the added "A" and "1".
Enjoy many happy times with your Thompson!
