1935-45. Stamp. Three known colourways: black, deep blue, brown. 28.5x26mm
A stamped mark on ware without an original backstamp. This is because this was used on ware specifically designed and made for Gray's Pottery, often by Kirklands or Winkle & Co. Note that Kirklands production was concentrated at Burgess & Lee in Burslem under the wartime Concentration Scheme.
