Victorian machine threaded ruby glass bowl with uranium rigaree

This Victorian glass bowl is made from clear glass covered with very fine, ruby machine threading. It has an applied rigaree in uranium yellow glass & applied crest also in uranium yellow. The bowl measures 7.5 cm tall, 14 cm across the crimped top rim, & 6.8 cm across the base, which has a neatly polished pontil mark. I feel quite confident in attributing this to an English manufacturer, perhaps Stevens & Williams. It probably once sat in a silver plated stand.
