From 1867 a letter system was also used to indicate the year of manufacture. This series of codes continued until the 1960s when the dots are arranged around the R (signifying registered) in a circle.

From 1966 the date coding system was rarely used and from the mid 1960s, a different format of factory stamp was also adopted for bone china tableware.

The date included is the year of introduction of the design, not the date of manufacture.

In April 1988 a system of year of manufacture identification that fitted with that used by Spode was introduced and an M within a diamond was incorporated below the factory mark.
