Wine glass (6) - Glass - Regency / William IV

A fine matched set of six early 19th-century English hand-blown Bristol green wine glasses.
Each glass has a plain round funnel/conical bowl above an elaborate knopped stem, incorporating multiple annulated collars and a central baluster-form knop, raised on a broad circular conical foot.
The glasses display the subtle variations expected of individually handmade early 19th-century glass. The pontil treatment and construction are consistent with period hand manufacture.
