As much of the output up to, during and in the first seven years after the war was produced for export, only seconds quality or undecorated surrey shape ware was available to purchase in the UK. Unfortunately a piece could have been potted and then stored away for years before actually being decorated.However the King Street Factory was taken over in 1935, and there would have been a period during which both factory mark styles were used. Some of the factory marks include registration numbers.The second image shows an Osmaston Road factory mark on a coffee cup and saucer also in pattern number A67. These are an indication of the date a pattern is first registered, but the actual piece could have been made some time afterwards.
Anyone requiring detailed information on this topic is advised to read the excellent paper by Ian Harding in Journal 6 of the Derby Porcelain international Society 2009.As a general rule, if the factory mark shows a vertical "ENGLAND", the piece was manufactured after 1890 and before 1923 and is not likely to appear in this website. Patterns such as 1128, 2451 and "Mikado" were produced throughout the period, and will therefore appear with more modern date ciphers. Ian Harding also includes images where factory marks include both the vertical "England" and the "Made in England" lettering.The "Made in England" is in a slightly different colour and seems to be a later addition.In this section I have included a selection of factory marks for the period 1927 onwards.This website deals only with ware from the Osmaston Road Works.
