The mark shown above was used from 1889 to 1902, and it includes a date code, in the form of a letter, under ENGLAND, which indicates the year of production.
A for 1891, B for 1892, C for 1893, and so on until L for 1902, the year in which the Grainger porcelain works were shut down.
Royal Worcester used a set of dot markings, starting in 1891, where the number of dots on either side of the crwon or among or below the words of the backstamp indicate the year of manufacture of the piece. 1893 had two dots, one on either side of the crown, and so on, up to 1915, where there are twenty-four dots, six on either side of the crown in two rows, and twelve beneath the words.
The number of dots indicate a the year of manufacture of the piece. In 1916 RW started adding other symbols and marks to the dot code. On egg coddlers, it seems that they stopped using the date codes early.
In many cases, we may refer to a backstamp style by the type of coddler upon which it was seen.
However, two types of coddler, or two sub-types of coddler, are distinguished from one another by the combination of backstamp impression, color of the backstamp, method of application of the backstamp to the coddler, material and spacing of the screw threads, and other discernable differences in manufacturing process or visual characteristic, other than the pattern.
There are variations of the major types that we will call sub-types.
