It is hallmarked to the handle- date letter'B' a lion passant without a crown and a King George head. It is hallmarked to the lid - lion passant, initials WB and a date letter'a. I can see no hallmark to the teapot body but it is clearly solid silver and I guarantee this. On one side of the body there is an engraved walking horse.
The teapot is 12 inches long and 7 inches high. I have left it unpolished. Couple of tiny dings to the body. A small hole near the hinge where the lid joins the body (photographed).
