Hi, can anyone help me identify this glass bowl or vase which I’ve had about 15 years? The closest I can find is Thomas Webb bullseye glass but there are no markings on the base of my bowl & I thought Webb’s glass usually had an engraved mark. I bought it from a house sale where a lot of the glass was Scandinavian. Height is 7 inches (18cm), dia 8 inches (20cm). Thanks
