hi - if your assumption is based purely on the evidence of machine etching, then the answer would be no -
machine acid etching was continued for many years into the C20 - although that doesn't mean this particular piece isn't from the very late C19 - it is possible.
I like the pattern by the way - very attractive.

Hopefully Patricia will have the time to look in on your glass, but I have a feeling this is one of the 'wishful thinking' group that whilst looking as tho it should be a bulb vase, almost certainly isn't.
