more good news, i even got a reply from the V & A
thank you for your enquiry. I have shown your photographs to our expert
in Glass, who agrees that your vase is indeed Venetian and dates from
1870's to 1900. It might have been made by Salviati or the Compagnia
Venezia Murano, but he thinks it could also have been made by one of the
other Muranese firms- as these often copied each others designs and
models. The foot has been off and might be a replacement.
I hope you find this information useful.

Hmmm, what to do next
