I’ve been working on restoring brake disks and have found some codes stamped on them. They don’t appear to be date codes to me. Anyone have a clue what they mean? Right now I have a NOS K1 disk holding a place on #97 until I get a disk refurbished. I should have kept track, and maybe it doesn’t matter, but any opinions which one may have come off #97?
Some of the numbers are hard to read and don’t turn out well in the photo but here’s what I think they are.

Because it's a security part, I think it's traceability codes from the manufacturing station to assembly at the factory... because there had to be a test to check the resistance and the veil after assembling the disc on its aluminum support...
But that's just my thought... ???
