not an epergne shape that I've seen previously Mel...... but doesn't mean it isn't - with definite epergnes more often than not the rim shape is some variation on a frill, and they were smaller. There were often several holders on the one stand - it's always possible this came as a single tube on a stand of sorts.
S. & W. did produce epergnes, mostly during the Victorian and Edwardian periods when these things were popular - although from what I can see they were not remotely like this piece which looks possibly to be later in style.
May we see the other end please.
