Vintage Antique Rex Oval Clear Glass Prescription Bottle with Cork Stopper

vintage / antique (?) clear glass prescription bottle branded Rex Oval ~ trademark reg complete with markings down one side with cc's (cubic centimeters), and the other side with, I think, oz's (ounces) the stopper is a marriage that I added, it fits, but I don't think it would stop liquid from escaping in excellent vintage condition measures approx 6.5" tall, approx 2.25" x 1.25" base
