Exhibit Antiques has dated this piece to the 1750s.
A superb English lead mid 18th-century Export wine glass in pale green. It has a large Ogee bowl engraved with a continuous fruiting vine.
Conical foot with a snapped pontil.

These glasses were made in England for export into the European market.
You can see an almost identical unengraved example in 'Coloured Glass by Derek C David and Keith Middlemas' where they show a selection of Export glasses from the mid 18th century on pages 22 and 23.

A wonderful example which we have never had in the last 20 years.
