I have a complete set of dinnerware (dinner/salad plates, soup bowls, soup tureen/ladle, vegetable dishes, platter, gravy boat) that have the following mark: Gordon Rd. No. 30671 Stoke on Trent quiver of arrows with Ridgways on it with a bow. I’m trying to date this set but having no luck. Blue on white transferware with flowers/foliage and framed outdoor scenes. Anybody know about this? Thanks!
