Who made this vase?

[La Spezia]

Hello,
2nd day in this forum and at once I am asking for your help.
I have a few Murano vases I can´t ascribe to a company or designer, only speculations.
In the near future I will aks you one by one for your help.
On each request I will post a new thread.
Thanks a lot for your kindness.

Horst
