Topic: Art Nouveau? Glass I.D. Help!!!

[mat74]

I recently bought this item in  a charity shop but am having trouble identifing it. It is approx 170mm tall with an opalescent sheen and flowing acid etched? lines. It is quite weighty at 900g and has an unpolished pontil.
Any help/ideas much appreciated.

It looks very like a Sanders and Wallace vase to me but I would have expected it to be signed somewhere, very small script on the base?

Interesting thanks, but nothing on the base.

here's one that is signed.  I think yours could be by Sanders and Wallace but escaped the signing maybe?  How does yours compare at the neck and rim?  There are definite similarities between the two but I could be wrong.
