I was browsing a shop with an assortment of items, and spotted this safe. Upper 2 doors open, but lower locked and no combo. It's sort of an interesting piece, and maybe I'm sort of turning into a collector, since I can't seem to get it out of my mind. I was in a bit of a hurry, so I didn't look at it carefully, but any info or ideas of its purpose would be helpful.
