In the 1970s or 80s we purchased some beautiful china from the store across from our hotel room on the left bank (Rue de Ecoles?) It was primarily a restaurant store but they made a set of tableware for us. The back says Porcelaine de Sologne and there is like a french horn and a 4 on the back. Inside the horn is Made in France. The pattern is one we saw often in the small country hotels/restaurants which we visited. A lovely peacock sits on the branch of a flowery tree in the center, and those flower branches repeat on the sides of the dishes. Dominant flower color is a medium purple. We’d like to add cups and saucers to the set we have. Can anyone help?
