I would appreciate your help in identifying the country and age of this large goblet. My guess is continental c1750s, but it could be a later reproduction, or that the engraving is not contemporary with the glass.
The goblet measures 8 1/2 inches tall with a 3 1/2 inch bowl and 4 1/4 inch foot. The stem is hollow blown with some nice knops that are reminiscent of Silesian stems. There is what appears to be an inch-long piece of charred wood within the stem itself, which has given the upper part of the stem a sooty/dusky appearance. There is no way to know if this is deliberate or not. Sorry - doesn't come out on the photo as I took it against a black background. The glass has a folded foot.
The engraving not very fine, though well executed. There is a large armorial crest on one side, and what appears to be an arrangement of flowers on the other.
Many thanks for your help
