I've discovered that another one of my medical cabinet had the locks replaced at some point as I suspected. There are two holes on both bottom and top of cabinet for the doors and the way I found it with the locks seemed very odd and not original. While researching the company that made this one "M. Weiss & Co" I came upon a couple of them for same with an odd lock which I am sure is original and what mine should have. I can't quite make out the name on the inside from the photos but I contacted the person that had the photos up. At any rate I thought I'd post it here as I've never seen any lock like this before and hoped someone could shed some light. Thanks! Click image for larger version.
