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.
RW nor any other authority on porcelain or pottery will have the faintest idea what you are talking about if you say you have a Type 2A RW egg coddler.
The characteristics of a coddler that are used to determine the type of coddler are the backstamp and the screw threads.
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.
All Type 5 coddlers have the finer-pitched (tighter, or older) threads, except Type 5E.
