A little while back, I purchased a gun in a period case that was missing the key.
I found a place on the Internet that made keys - and apparently sells lots of other stuff - so I shipped them my case lock.
Apparently the lock needed not just a key, but a piece was missing.
I'm very excited today, to have received the repaired lock with two keys. I reinstalled it in the case and we're good to go.
Thought y'all may be interested if you need a similar service.
