Perplexed....Aluminum box with "combination" and colored glass

I am totally stumped as to what this is and I've stumped other "experts". This is a cast aluminum box with 3 sliding panels inside. Each panel has an opening in the center and colored glass on either end. On the front of the box is a "combination" and what appears to be a Star of David.  I have talked to many people and have done research and can find nothing.  There is, what appears to be, a serial number samped on the box.  It is "BS-9263".  The only other identifier is a stamp on the lead seal tags that the box is sealed with.  I have more pics avail if anyone wants/needs them.
