Hi All. Hope someone can help. I found this controlled bubble small vase in Yorkshire recently, somewhat similar in shape to Whitefriars 9435 but not the correct size (this is only 6 3/8" - 16 cm). Not sure if the pontil is moulded or polished - there are some slight 'ripple' marks running across the pontil. It weighs 375 gms. Anyone any ideas?
