W. Adams "Empress" Ironstone Tea Pot, made in England. For Sale

William Adams and Sons "Empress" teapot in excellent condition. There is no evidence of chips or cracks and the glaze is intact with no crazing. The lid fits snugly.
I have been unable to date the backstamp accurately, but this particular style of backstamp was used from the 1950's onwards. As the Adams pottery was taken over by the Wedgwood Company in 1966, this teapot had to be made between those two dates.
