do the stamps on the botto? Do the Raynham stamps on the bottom of the vases have to be red lettering of the brand Raynham and black stamped number for the vase to be authentic? The vase I have just bought has the raynham stamp but in blue but, has a black stamped number? I know Bendigo, victoria bought the rights to make copies here in Australia and they have stickers and blue stamps sometimes....... Can someone who knows their collector markings please help me?
