Hi, cant find this shape anywhere and wondering if anyone could give me any clues as to it`s origins... The base is more domed than other pieces of Riihimaki, but the top rim is niceley polished and the shape is quite, er, complex ? Also with other Riihimaki pieces the clear casing is visible at the base. I am not sure that this piece is cased clear. Any advice would be most welcome, thanks.
