Won this from eBay. Has anyone seen anything like it? It was supposedly made by the guys at Hemingray. One side of the base is embossed HEMINGRAY -9. The other side is embossed MADE IN U.S.A. over 46-48:. It has flattened/ground off drip points and it is made of one piece of glass - not several pieces glues together. Have I got something unique here?
