Found this at a garage sale over the weekend and was able to pick it up for $20. I looked around the webs and I think this humidor sells for about $90 from CI.
I picked up some food safe clear caulking and plan to run a bead of caulk around the glass pieces and around the hydrometer mounted in the door. I was also thinking about looking into some sort of weather stripping for the door. At the very least it will be a fun little project to see if I can get this thing to hold stable humidity.
