FOUND THIS UNUSUAL PIECE, CANNOT LOCATE IN ANY BOOKS OR ONLINE RESOURCES. i BELIEVE IT TO BE DUNCAN MILLER CARIBBEAN CRYSTAL CIGARETTE HOLDER, IN THE TOP HAT FORM. THE SHAPE MATCHES OTHER DUNCAN MILLER TOP HATS. THOUGHT IT MIGHT BE ANCHOR HOCKING INSTEAD BUT THE GLASS IS VERY FINE AND CLEAR, THE BOTTOM RIM GROUND, AND THERE ARE NO IDENTIFYING MARKS ON THE BOTTOM. CAN ANYONE CONFIRM?
