This system continued until 1915 when 24 dots are arranged around the standard printed mark.
The dots system was getting a little clumbersome so they were replaced
by a single asterisk in 1916 which was then followed by a new dot
sequence. All under the circle.
From 1916 a small star or asterisk appears below the mark.
1916 * below the mark. 1917 * and one dot. 1918 * and two dots
However on some pieces the old dot sequence continued for a few
years, it being easier and cheaper to put an extra dot on existing
copper plates than make new ones. This continued until the dots
became un-manageable and then worcester marks changed to different
shapes, all printed beneath the circle.

This continued until 1941 when there were 9 dots and the triple circle mark.
From c1942 the vast majority of factory stamps were printed in
black with the following codes below the mark.
1942-48 no dating system was used. 1949 V. 1950 W. 1951 W. 1952
W. 1953 W.
In 1949 the various asterisk, square,
diamond and circle shapes changed to letters and then quickly back
to letters and dot sequences. These continued until 1963 but their
use was rather inconsistent and a great many pieces produced at
this time un-dated.

After 1963 no dating system is used but patterns are all named
and bear the date that they were first introduced.
This continued until 1963 when 13 dots are arranged around the
W. After 1956 the letter W was nearly always substituted with a
letter R in a circle, i.e. 1959 = R or W under the circle with 9
dots.
From 1966 no date coding system was
used, but on tableware the year the pattern was introduced is stated
next to
the pattern name.
In 1974 the current format of factory
stamp was adopted. 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.
In January 1989 new factory stamps
were phased in with N in place of the M and soon afterward black
numbers were introduced. These numbers were replaced with grey ones
in August 1989 to reduce their visual impact.
January 1990 a new system introduced a printed grey lithographer
identification number plus a suffix to signify the year.

reverted to the R form under the mark.

Royal Worcester Tableware Marks
At some point during the 1960s it became standard
practice for the Royal Worcester factory to name all their tableware
and dinner services. The Evesham and Royal Garden patterns being
just two examples.
Prior to this date named sets were uncommon, although
there were some the majority of early named patterns were given
the name in more recent times. Rather than use names the Worcester
factory relied on pattern numbers which were hand written in script,
rather than stamped.
In the 1860s when
Royal Worcester was formed from the earlier Kerr and Binns, tableware
was given a simple four figure pattern number which carried on from
those used by both Kerr and Binns and the Chamberlain factory.
Numbers begin with 7247 in mid-1862 and continued
to 9685 in August 1876.
From 1876 they changed
to numbers prefixed with a ‘B’ and these ran until B
1081 which was produced in May 1883.
From 1883 all new
tableware patterns were prefixed with a ‘W’ which started
with ‘W1’ and contimued until at least ‘W9978’
which was probably produced around mid-1913.
Prefixes then changed to a ‘C’ and
the numbers started again and continued up to ‘C3390’
which was first produced in 1928.
From 1928 all tableware
patterns were prefixed with a ‘Z’ which continued until
after 1962.
Records were only published for the more expensive
hand painted patterns which appeared randomly throughout the numbering
sequence.
The records detail tableware type, the decoration,
and the painter, but the simpler apprentice sets and transfer printed
sets appear to have no clear record of what each set looks like.
