Funny tag on fender- what is it?

So I’m going thru a bag of stuff for my 72’ Demon and I find this tag I removed when I got the car. It was attached to the fender tag and even though it’s hard to see... if you place the tag horizontal it is sectioned vertically. 1” X 8” thing gauge sheet. Painted body color.
Going left to right-

I will assume it is some sort of inspection tag and the codes designate who inspected the fit and finish. But can anyone confirm my findings?
Thank you in advance-
Joe
