James Ryals

Trying to find information on a silverware set given to my husband by his grandfather. The set is made by James Ryal made in Sheffield England. It has a heart and diamond on the each piece. It is a silver setting for eight. On the bottom of the wooden box that holds th silver set, it has in gold Brit. Reg nb 869455. I have tried googling on James Ryals but have not been able to find out anything much about him. Anyone out there know anything about him or how much his silverware is fetching these days. Thanks Much
