part # on mounts?

[Two"85s"]

I revived some bike side mounts for a GL1xxx from a kind person that has allow me to make patterns
that I might reproduce them. In the course of my work I have found all save one has a nine digit ( part)
number stamped on them. I also found them mark "V-8-31-81" this was added with a handheld engraving
tool. Maybe another way to track what brackets fit the common bikes of the time.

I just though I would share!

Looks like a date.

This number is on all three of my brackets.
