The Piccadilly shape is made up of Brittany flatware - plates, platters, bowls, and saucer. The hollowware is made up of five specially modeled pieces; covered sugar, creamer, covered casserole, teacup, and sauceboat. They were made with cylindrical bodies with flattop handles and a sight foot. All five were modeled in December of 1939 and were immediately released into production. Before the name Piccadilly was applied to this new shape it was referred to as "New Brittany."
The treatments used on Brittany and Piccadilly might look very similar, but they're not identical. Both lines make use of silk screen and decal combination patterns popular in the late 1930s and early 1940s.
Flatware is marked in the same manner as Brittany with a general HLC backstamp, however the hollowware was given its own special marking.
The line continued production until the early 1950s. There are mold notes regarding minor alterations to the sugar and casserole lid, but from beginning to end, Piccadilly remained largely unchanged.
