The Royal Doulton Stamp is an important piece of information when you are deciding to purchase, bid or make an offer for.
I am mainly talking about the backstamp on Character jugs as alot of people are not too fimiliar with the backstamp and what it means. I hope this guide will give you a better idea and you can then make the choices on which piece you will go after.
In the 1930's doulton had decided that they would start registering there designs to stop them being copied. They registered then with the UK patent office and often resulted in registration number id printed underneath the backstamp. The year the jug was registered can be worked out from the table numbers published with the patent office. Most cases registration was a year before the jug went into production. It should be noted to all buyers and collectors that the registration number does not give the date of manufacture for a specific piece but only when the design was first protected.
By the late 1930's the names that appear of the jugs were now inverted commas was usually included above the registration number. Jugs that were produced during the 1930's might also have a hand painted D pattern number which was addes by the decorator when the jug was completed. This practice continued until the second world war.
The only way to determine the exact year of manufacture is with the date code if it has one of course. This numbering system began in 1928 with the number one. The date-code number is immediately to right of the lion and crown symbol (stamp) and the year of manufacture can be calculated by adding it to 1927. Thus the code 11 will give you a date of 1938 and the number 15 indicates 1942. This code system can be found on character jugs from the 1930's and 40's.
Now the A mark on the left side of the lion and crown symbol is known as it's kiln control mark denoting a specific type of eathenware body known as Georgian. Sometimes an A mark appears on a character jug without any other information. This was in the 1940's and 1950's. It was used on a variety of Royal Doulton products between 1939 and 1955 so its presence on character jugs will date the piece to within a time frame.
In the 1980's and 1990's a large elegant script was adopted for the character names in the early 1980's and by the 1983 the first reference to hand made and hand decorated had been included underneath. An entirely new design of backstamp was introduced in 1984 featuring the new styling for the company name Royal Doulton, the subject of the jug in bold capitals, the modeller's facsimile signature and the words "hand made and hand decorated" forming an arch around the lion and crown. These changes were implemented in order to acknowledge the talents of individual artists and to seek public recognition of the specialist production skills involved.
Initials or dots and dashers on the base are decorator's marks but no records exist to identify these.
I hope this has helped you understand the stamp that little bit more and continue your search for those great pieces that are out there.
