Old Chess Set

I have an old Aztec/Mayan Chess Set with wooden drawers that have carved horses with scenes on all four sides to tell a story of the Mexican/American War, the chess pieces are hand carved by some sort of valuable stone. The chess board itself has horses in every square. I have tried several antique stores in my area and none of the experts I've spoken to have seen a piece like this or know of its age and origin. I'm stumped at the moment and hoping someone can shed some light on this piece I have.

Good
