these are just thoughts , not that I know anything at all about Venetian/antique Murano glass.
The shape matches
The size is different being about 3cm taller than yours
The decor is different.
I have only one piece in a similar vein i.e possibly late 19th/early 20thc and it is impeccably made. I think it's late 19th early 20thc Salviati or Barovier However, the V&A have said words to this effect (amongst other things)
- whoever made it certainly knew how to copy 16thc glass
- there have been recent reproductions of old glass
And they cannot commit on who made it or date it.
From what I can see this is a complex area
- I'm hoping my newly acquired damaged piece is original but I wont know until it arrives and can see it more clearly -even then I might not know I guess
