Paul, could we get a shot showing the face profile of the elephant. I suspect it's one of the kind that we may not be able to tell who made it. So many companies, both famous and obscure, made elephants in this pose. One thing I noticed is the separation of the feet, so I did consider Archimede Seguso. If we could see the profile of the face, it would be easier to tell.
Gold was used so commonly in Murano glass that it is, as you mentioned, not very helpful in identifying. The gold did make me think probably not V Nason because they didn't use gold too often. So many other companies did. I hope the face will tell us something.
