I can't decipher all those letters, but since YOU have access to the decal in-person and in all sorts of lighting, maybe you can...but there's a few that could be "GNAC" which would lead some of us to a word like Salignac, not Italian but French. If that's even close I wonder if you're 100% certain that it's Italian. There certainly are some Italian towns that have French history (conquest and rule) and have retained some of those place-names and spellings, but you might also have an Italian-made product that was sold in France.
Or, more likely those letters are something else entirely that YOU have to decipher (or take better pics).
