Thank you. It's interesting that you concur.

...my understanding of "wrythen" is that it refers specifically to 'raised moulded lines in a spiralling or swirling pattern' - as on the bowls of some old drinking glasses.
Exactly so, thank you and so much better put than I could have done.
Back to the original item...
I note the seller doesn't actually say it's English but of course if isn't then ...what ? where ? and when ? become more perlexing questions. But perhaps there are some explanataion(s).
Ray, isn't it possible that the blank was Czech / Bohemian even back then ? Then the engraving done here in England ?
The only comment I have on the glass is that it seems surprisingly thick.
What is it about the engraving that doesn't seem right to you ?
I would have thought that some historical research into excise revolts would bring up at least a broad timeframe to which the engraving purports to refer. Going by the bidding it would seem that at least some bidders think they know.
