A green bowl with vertical optic ribbing, quite raised on the outside - almost like fluting - and much softer to the inside of the bowl. The ribs end at the top rim with a counter-clockwise twist.
The applied foot is plain green glass and has a very short 'stem'. It's finished to the base with a slightly off-centre and slighty irregular polished pontil mark. It also has a huge amount of base-wear.
It's 120mm / 4.75" tall and 195mm / 7.75" in diameter.
The colour bears a resemblance to early Whitefriars colours, although it doesn't appear to be from their stable. The goodly folk at the WF boards have suggested Stuart and S&W as possible contenders. The design certainly feels 1920s - 1930s.
Any comments and thoughts gratefully received.
