Dirk, do you know if the Taube one's came in opaque cased (like the green one)?
Sorry, Wayne, I´m not sure... I
think I´ve seen them painted also - looks quite ugly after
a few decades with the paint flaking off. I´ll keep an open eye for cased ones - in case they exist...

The similarity to the Empoli ones is strong, but the balls on the Taube vases / candlesticks seem to
be more pronounced, with an almost straight cylindrical part between them. Also the part towards
the top rim is more wavy on the Empoli ones.
