Thanks

The design of the enamelling reminds of of Bohemian glass. This scroll and rococo type decoration appears on lots of bechers I think.
The design on the snake I haven't been able to find though, I mean the design shape of the 'scales'. So far most seem to be gilded and are slightly different shape of scales.
Also most of those I've seen have indented eyes on the snake so far. Yours are enamelled on.
Lovely piece

Will be interesting to find out more about it.
Also with the body /lower neck cut into shape as well. A bit different.
Could the 'enamelling' be pewter? I think Harrach used pewter decoration, so it could be pewter perhaps giving it the strange colour effect.
