Many thanks for the information, Jonas. This vase seems to have slipped into obscurity as I have tried countless searches on the internet without a result, other than an eBay seller in USA who is selling one. He also, has had trouble finding a reference and doesn't know it is called "Wing". ! Bertil's own website has a gallery of images of his work, about 18 pages at 6 images to a page but there seems to be a gremlin after page 4 and you cannot progress past this. Very frustrating! Thanks again, Jonas for your input. Kind regards, Barry
