I'm happy to be a new member, and I hope someone can help me with this one tea set, which I'm told is early Clews, but it doesn't have the appropriate imprinted maker mark. Certainly has the age, and looks like other pieces I have of Clews, same glaze, same border patterns and florals. Can someone provide a bit more info on this beautiful old set, please? The only mark is the glaze mark, STONE CHINA. TIA!
