This goblet is somewhat of an enigma to me, and I am looking for further information on it. The goblet itself appears to be a genuine Georgian one c1760, but the engraving may have been added later.
The goblet is good quality (bright ring, etc) and measures 7 inches tall with a 2 3/4 inch bowl and 3 1/2 inch foot. There is a somewhat naive engraving of a boat above which are the words 'Success to the EAGLE FRIGATE Privateer. The elongated S in "Success" doesn't look correct - rather like a modern interpretation, without the bar. There are some very well known Eagle Frigate Privateer glasses, but the ship and text on this glass are not the same style and quality.
I noticed an almost identical glass in Christie's Sale 5068 (8 Mar 2011), described there as "The glass circa 1760, the engraving later", which did not seem to deter the bidders unduly. Actually, it is a very handsome glass! A similar glass (possibly the very same, else there could be a few about!) appearing on Antiques Roadshow (2012, Lullworth Castle) with a consistent description.
Assuming the glass is correct, does anyone know when the engraving was added, or by whom?
Best wishes, Simon
