Hi. Anyone any ideas about this green cased vase. Found in the North West of England it measures 20 cm tall x 9.5 cm wide x 7 cm deep and weighs almost 1500 gms. Ground out polished pontil. The green is (in my opinion) very similar to Whitefriars Ocean Green but I've spent days searching for Whitefriars Ocean Green with no success so I'm making the assumption it's not by them. I've also tried many many searches for Scandinavian makers with no success. Anyone any ideas or pointers? Much appreciated. Thanks
