I just spoke by phone with both Royal Doulton UK and Royal Doulton United states regarding this issue.
A little confused myself, because I have been collecting and also selling this china pattern for sometime, I sought an answer to the belief that no further Old Country Roses products were manufactured in England.
Here is the answer I received on both sides:
If a NEW product is manufactured in the United Kingdom, the manufacturer must place a sticker on that item stating where it was manufactured. Not all pieces necessarily state "England" in the back stamp if they are new.
If a Royal Albert product is manufactured elsewhere, the manufacturer also requires a sticker. The other factory is located in Indonesia.
There is, in fact, currently stock being manufactured and coming out of England, however.
Verified through manufacturer that this piece, although the back stamp does not state "England," was manufactured in the UK because of the clearly labeled sticker and bar code attached by the manufacturer.
Closer view of the manufacturer's sticker and bar code...
Therefore, if the sticker is absent from the product itself, we cannot really be sure where it originated most of the time. If the sticker is absent and the backstamp clearly states the location, then we can be sure of its origin.
This guide applies to newly made Royal Albert Old Country Roses ONLY and was created 9/21/2007, the date of my telephone calls to the manufacturer.
If you gain further reliable information and would like me to add to this guide at a later time, please contact me. Thanks!
