My teen has a half dozen of the classic MASTER
combination locks which I'd like to re-use for my PE for
my grade schooler, yet the teen doesn't remember the
combination to any of the padlocks.

They're the classic colored-dial Master combination locks.
They're all locked but not locked to anything.
There is no serial number that I can see.
It just says "Hardened" on the hasp.

Is there a method for finding the combination?

Take them to a locksmth.
