not being too bright at understanding the Board's locations I posted the details you see below into what I assumed was 'British etc.', only to spend half the evening being unable to find my contribution. I'd overlooked the fact that due to the nature of the original posters comments, the entire thread had been relegated to 'Market Place'.
Anyway, on the assumption there might be some soul with nothing to do and who might wish to read my words - here they are.
Am also including the 'Market Place' link - it may be of interest showing, as it does, related comments regarding Stuart's 'Waterford' cut pattern..................
http://www.glassmessages.com/index.php/topic,59680.msg337199.html#msg337199""At least I think this one is 'Waterford' - there seems to be some variation in what might loosely be described as a butterfly outline - a large rectangle with a substantial mitred cut within each of the four segments, producing a sort of 'four wings appearance'. Of course, if someone knows it's some other pattern shout quickly.
The backstamp is simply the word Stuart - no England - and the final t has a wrigley tail. In view of the lack of staining, base wear and good overall condition - combined with the type of backstamp, then I'm going to suggest the date of manufacture is around 1950 - 60.
It will no doubt go back out to the charity shop very soon, but for £2.99 I couldn't resist it.
I was tempted to suggest the shape was a form of bludgeon, but now not sure, and it could even be something rather obscure called a 'Taper-globe' - an Anglo-Irish form made originally c. 1800 - 1820 - a hybrid derived from the taper and shaft-and-globe - but there other folk here much better at decanters, and they may know correctly which shape this is.""
