My mother says she acquired five mixing bowls and two jugs from Grainger and Faulkner, Singleton, in 1956. One of the bowls broke, the second smallest.
These are all in the same pattern, a plaid design, and were made by Villeroy & Boch. The bases are stamped with the company name, the word Mettlach, and say they were made in France-Saar Economic Union.
I want to acquire the rest of this set.
I'll post some pictures of what I have when I get the chance.
