Hmm that china is very nice. You could possible Google search for "china featured in Downton Abbey". Beyond that, you would probably have to get info from someone on the show.

If anyone finds the answer to this, please post it!

I am very interested in China and I would also like to know the name of the China pattern

pictured in the Opening Credits. 

According to this article the family china is the family crest added to Spode china. It doesn't say what pattern though.

The tea service appears to be the china that I've had since 1971.  It is Royal Doulton English Renaissance.  If you google it, you'll find photos and websites where you can purchase it.

Thanks! I think it is so beautiful.

I would like to know the China Pattern that is shown in the opening credits of every episode.

The China is White with a simple border that looks almost yellow, not gold, with a scalloped edge.

Does anyone know the answer to my question?

Thank you!

Is this it?

I would love to know the china pattern used when Matthew opens his letter from Lord Grantham. I've never seen such fluted plates. Scalloped, yes, but not so "wavy."
