Someone had one of these on a site I looked at and side it was a jewelry box.  I'm more thinking it is a cigarette case.  Box is so unique, it opens on the top and also the bottom slides out.  Still has the original paper lining which makes me think it was a cigarette case.  Box 4" X 3 1/2" and 2" tall.  Is really tarnish, but I like the antique look.  In excellent condition.
