A George IV silver wine cooler, apparently Jonathan Briggs & Co, Sheffield, 1827

assembled from richly detailed die-stamped parts, later engraved with a crest on either side, plated detachable liner

The later crests clearly replace earlier engraving and on one side this has caused the already thin silver to dent. There is evidence of some small repairs to stem, which has interfered with the marks, especially the maker's mark.

Highly wrought die-stamped silver bearing Sheffield marks of this date is more usually associated with the work of Robert Gainsford.
