The backstamp on Type 3 coddlers is dull green in color.
George Grainger took over the business when his father died in 1839.The company was taken over by the Worcester Royal Porcelain Company, Ltd. 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.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.
