Swedish Mauser 101 ... what's that funny disk thingie for?

IIRC, this brass disk indicates that the bore of my Swedish Mauser left refurb at 6.48 mm (the triangle mark above the 8 in the 6.4 line) and was in condition '1', indicated by the small triangle above the number 1. '0' was the best rating for bore condition and was indicated by having no triangle mark.
Am I correct, and is there anything else to be gleaned from this disk?
Hey, I just noticed a second, lighter strike above the 9 ... what's that about?
