after more research, ive found that this lock is prob not a novelty item,
so i think maybe? IM WRONG
the lock that akl439, has is prob a very old lock
not a brain teaser, novelty item, that i thought it was
have not found away to open it yet, still working on that

proof of my mistake

...have you tired attaching a stethoscope to the device, and 'listening' carefully to the tumblers?

Otherwise you'd literally have to check EVERY letter combination. There's no reason to believe it will be a 'word', solution.
