British silver plate marks indicate electroplated items made in the UK, with specific symbols and systems used by British manufacturers to denote quality and origin.
Companies like Elkington, Mappin & Webb, and Walker & Hall developed their own marking systems for identifying their silver plate products.
British manufacturers used various quality indicators including A1, AA, and specific weight markings to denote the thickness of silver plating.
Many British plate items carry registration diamonds or pattern numbers that help date items and identify manufacturers.
