Hi Burnisherboy,
Just to add some background:
British Plate
A composite metal, developed c.1835, of a thin sheet of silver fused over a core of a Nickel Silver (instead of over copper, as for Sheffield Plate). It was harder and more durable than Sheffield Plate, had a colour and lustre similar to silver, did not reveal a pink tinge when worn, resisted acids, could be fused with hard solder, and required less silver for the coating; consequently it largely supplanted Sheffield Plate, but in turn was superseded in 1840 by ware made by Electroplating. Articles of British Plate were made by stamping sheets with a drop hammer and soldering them to form the desired piece, then adding mounts of silver either stamped or, later, made by Electroforming. It was used to make all types of articles that were made of Sheffield Plate. British Plate had no legal hallmarks, but was often given marks resembling silver hallmarks, usually not by the makers but by merchants, thus violating the 1772 and 1819 laws forbidding the use of marks on plated ware except those registered at the Sheffield Assay Office; the law was not strictly enforced, and a number of deceptive marks have been noted. The ware was sometimes advertised as 'plated by fire' to promote its sale over electroplated ware. See: G. Bernard Hughes, 'Successor to Sheffield Plate' in 'Country Life', 28 January 1960, p.160.
