Art Deco Poole Pottery Candle Holder

This is a recent acquisition into my Art Deco collection. This double candle holder was manufactured by the British firm known as Poole Pottery, circa 1930's. A lot of Poole's ceramics had more colorful glazes and graphics, but John Adams designed a line of mottled or monotone glazed items for the company during that period. This swirled or nautilus design is likely a John Adams or Harold Stabler design in the "Seagull" color, but I'd love to hear more information about it if others are familiar with Poole Pottery. It is impressed on the base with a "Poole England" mark with the number 976. It measures 6.5" wide and 3.5" high.

The color is sort of a white, stone, grayish color. Does anyone have any expertise in Poole Pottery and could provide some more information?

Collector Rob has a similar one on his blog:
