A Mappin and Webb Prince's Plate Silver-Plated Cylindrical Component

A silver-plated cylindrical object manufactured by Mappin and Webb. The item is produced using Prince’s Plate, a proprietary high-quality electroplating process developed by the maker. The design is functional and understated, featuring flared, rolled rims at the upper and lower edges. The base contains a central circular aperture, suggesting the piece may have served as a socket or mount for a larger assembly. The underside is stamped with several marks: a diamond-shaped border containing the letter H, the name MAPPIN and WEBB in serif capitals, a shield-shaped border containing a stylized letter W, and the words PRINCE’S PLATE. The pattern number W20720 is stamped at the bottom of the mark sequence.
