Hi, i found this pair in a charity shop!! They are about 8" tall with a ground out pontil which is unpolished, rough in fact. They depict a windmill, a bird and I think a couple of sailing ships in 3 segments with grapes and vines in the other 3. The necks have no sign of grinding for stoppers and they have a pair of lug like handles on the sides of neck. I would think they are pretty old and possibly Dutch because of the windmills. They are certainly very interesting, distinctive and I would love to have some info about them, TIA Wolfie
