This backstamp consists of a W in a circle, the words ROYAL WORCESTER PORCELAIN, and MADE IN ENGLAND.
This backstamp is like the previous one, with the addition of the Registered Trademark symbol ®. The difference between these types is determined by the material that was used to manufacture the screw threads of the coddler.
There are older coddlers and backstamps made by RW, but this is one that is seen most often of the older backstamps. This backstamp, consisting of a W in a circle, the words ROYAL WORCESTER PORCELAIN, and MADE IN ENGLAND is found on coddlers of Type 8 and Type 9.
The difference between the types can be determined by the color and placement of the backstamp.
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.
In some cases there are additional words stamped or superimposed onto the basic design.The backstamps of Type 5 coddlers all have the stylized script W in the center of the circle.The subtypes are distinguished by the words and placement of them in the backstamp design.In order to differentiate between different Royal Worcester (RW) coddlers with the same or similar pattern, We use a combination of characteristics of the coddler. As more data becomes available to us, some of these types may change.There are twelve major types of RW coddlers, which will be designated with an Arabic numeral (Type 1 through Type 12).
