Although we see most Victorian pressed glass items "unadorned", many of the smaller items were undoubtedly supplied, and displayed, with assorted metalware mounts, accessories, or fittings. Over time, most of the metalware must have become badly worn, damaged, or lost.
So, just for information, here are some images of a Percival Vickers pressed glass circular dish RD 80632 (1887) with contemporary (and presumably original) ornate silver plated lid and underplate manufactured by John Round and Son Ltd, Tudor Works, Tudor Street, Sheffield. The glass dish itself has no markings, but the pattern corresponds with that on a celery vase illustrated on page 49 of Jenny Thompson's "Identification of English Pressed Glass 1842-1908". Not exactly a case of 'gilding the lily', but what a difference Victorian plated bling can make.
