Cantagalli stoviglieri?

Sorting my recently deceased father-in-law's things, we found this set - a tureen, shallow bowl and platter - with a mark that looks like Cantagalli. It does not have "Italia" or "Italy", which I understand the pieces had after the Taft Act, and the signature is the same colour as the pattern and differs on each piece.
My FIL was a collector and I'm sure he thought they were genuine. It is my understanding that the Cantagalli mark was frequently faked. Any educated guesses as to its possible age and authenticity would be very welcome.

 

I think they're right. Searching online I see several examples of the same pattern, all called Canatgalli. They have the right look.










Looks like a pattern that should have a name, but I haven't seen one.

 

I'm sorry I can't say for sure but here are a few pages that are from the book From Cantagalli to Fornasetti by Walter and Karen Del Pellegrino. Walter was a member of this board and was so helpful but sadly he passed away. He had a site and I'll post a link to the section where he answered Cantagalli questions.

Walter also responded to several questions about Cantagalli marks here. Here are some where he discusses the mark.
