From 1922 or 1923 until the end ( presumably) of 1927 tableware appears bearing a mark that lacks the traditional crown.The reason for the introduction and use of this new mark is not known although it may have been nothing more complex than the need for a smaller mark to fit smaller wares.In Mark "B," the various letters and numbers reflect the following: the large "Rd" means "registered"; the Roman numeral in the circle at the top of the mark represents the type of material from which the piece was made (see Table 1); the Arabic numeral in the top inside section of the diamond represents the day of the month; the letter at the right-hand section represents the year the piece was registered (see Table 4); the letter in the bottom segment represents the month the piece was registered (see Table 2); and the Arabic numeral at the left-hand side represents the parcel number.In other words, this mark appeared on a piece of ceramics registered on July 7, 1873.This second use of the ‘standard’ mark is believed to have continued until about 1936.

It includes reproductions or fake marks on recent imports, which are shown side-by-side authentic ones for quick visual comparison.The mark appears not to have been used exclusively as there are examples of the earlier ‘standard’ Doulton mark that can be unambiguously dated to the same period.The earlier ‘standard’ mark with lion, crown and Doulton roundel was ‘reintroduced’ from 1928, but was supplemented by a date number related to the year of production.The mark was varied from time to time and the table below includes the major marks that appear on tableware manufactured at the Doulton (Burslem) factory (Series Ware and the Lambeth Stonewares often have special marks).The Doulton tableware marks are below the glaze (as is the decoration in most cases).

The date numbers referred to above also accompany this mark and for the period from about 1930 to 1936 examples of both marks can be found.
