OK, I've been using the thick pipe burying tape to protect the knurls during drilling operations. I did find a PDF for serial numbers. It does not have an exact year just a range of production.

Pipe tape is certified to be consistently 10 mils thick. That should make a nice soft pad that doesn't throw you off center! Good idea, better than a beer can.

That pdf is pretty cool.
I use Al & Cu to protect finished parts in the 4-jaw. I made "sets" for both ID & OD holding. Some people make nice cut out & formed slip on jaw protectors. I bought a sheet of Cu to make em too but I never get around to making them. Lol. They're not soft enough to fully protect the knurling on your Al bats though.
When I was making Ti beads & stuff I would make split collars out of delrin to protect knurling.
