A: William Harry Grindley founded his company in Tunstall, Stoke-on-Trent, England, in 1881. They made ironstone and earthenware, including flow-blue ware. Most of their wares were produced for exporting to the United States. The numbers “737554 — 737555” are British Government registry numbers that show your dishes were made around 1928. “Windsor Ivory” is the basic shape of the dishes and “The Katherine” is the name of the pattern. After several name changes and different owners, Grindley and Company went into receivership and was taken over by Woodlands Pottery in 1991.
Your set of dinnerware would probably be worth $250 to $350.
