It does look like an epergne, or flower stand - and the 'vase' part is large enough to hold a few short-stemmed flowers. Looking at Silber & Fleming, a lot of these single trumpet flower stands incorporated bowls that sat lower on the stem, and these would have held more flower heads or whatever, but this one doesn't have a metal screw to seal the join, so possibly not bowls.
Always possible that originally there was an additional part/s that attached in the area "where the plates would sit" - such as extra trumpets - these things often had multiple containers for flowers. The Victorians were mad keen on epergnes, flower stands, fern boxes and combination fruit and flower stands, so perhaps Chris is correct with his suggestion that a plate or two is missing, and they would have held fruit.
Is there any wear in the place where the plates might have located?? ............. and come to that what is the extent of wear under the foot - assume no marks or similar anywhere. If this were a table item and of the age suggested, then I'd expect to see considerable wear under the foot.
yes, inverted baluster (swelling at the top rather than the bottom), but not very pronounced so unsure if it really qualifies for that description. Are we confident of the reasons given for this to qualify for States production especially - had thought such features were common in the U.K. as well.
As to date - in view of the acid work then almost certainly not before 1850's (C.H. - page 175 in Brit. Glass) and doubt that we'll get any closer than 1860's to 1890's, although would agree that the Greek key does suggest 1860s - 1880s. Not easy to see exactly the style of this 'key' - it doesn't look similar to the M. W. key - but since the attached pix are against a white background then images unclear.
Clear glass should always be photographed against a uniform dark background.
To quote C.H. again............. "The correct identification and dating of 19th century cut glass is one of the most difficult areas of glass collecting............. "The situation is further complicated by the reproduction of patterns beginning as early as the 1880s, and continuing into the 1920s."
All a bit woolly I'm afraid, but just one of those (probably incomplete) things that will defeat exactness.
nice butter dish Chris - but think I'd want more proof of the age you're suggesting............ that criss-cross pattern must have been made for ever and a day by the world and his wife, although appreciate the Greek key is where you're coming from re the date.
