Hi

Whose signature is this on an Italian silver besamim box?

What I can say is that the 123 CO mark corresponds to the FALA company of Carugati Paolo, via Bernasconi 2 Cernobbio.
The company still exists, and at this address
https://www.argenteriafala.com/it/
You can read "Do not hesitate to contact us for any information on our products".
I sent an email with the image of the signature, but to date I have not received a response.
Best
Amena

Hi Amena

Thanks for trying.
