Pozzi - Table service for 6 (19) - Pottery

The service set consists of:
No. 6 flat plates, circumference 76 cm, diameter 24 cm
No. 6 deep bowls, circumference 76 cm, diameter 24 cm, depth 4.5 cm
No. 6 dessert plates, circumference 67 cm, diameter 21 cm
No. 1 pasta/salad tureen, circumference 74 cm, diameter 23 cm, depth 9 cm

I inherited the set from my mother, who took great care of it and whom I believe used it on very few occasions. I am unsure of its provenance, whether it was a gift from acquaintances or a purchase.
The colors are bright and there are no signs of wear or chipping on the rims.
I hope I have been thorough in my description.
