My Nippon book has marks in it from page 74-98 not included. Looked at fake marks & not there either. Maybe your mark hadn't been found yet. It looks like it might be earlier mark as 1 flower used & mountain in my book. Later used more "M" mark. There were several different companies that made it. Might help identify it if we could see the item.

Cordey was made in Trenton New Jersey by the Cybis company...I think Cybis..Cordey was known for that lace technique. They took real lace and dipped it into s liquid porcelain and fired....don't know how they kept the lace from burning.... I think you could easily ask $200 for the pair...perhaps more. But I don't think you'll get it...unless a serious collector comes in.

I can't see the marks as the picture appears blurry. R.S appeared on many pieces of porcelain of "German" origin...and bavarian and Prussian etc. Those pieces were made at the end of the 19th century and the beginning of the 20th....they were fine quality!!! The R. S. stands for Reinholdt Schliegelmilch ( check spelling!!) The looks of your pieces are consistant with the appearance or the RS Germany, Bavaria look....not as fine as the Prussian ware. I would really like to see a better picture of the back stamp....but it's a very lovely set...undoubtedly German/Prussian/Auistrian/Bavarian. Clearly late 19th century. Amd most likely from the Reinholdt Schleigelmilch factories. Linda C Here is a link that might be useful: a bit of history

The us zone Germany was made between I think 46 adn 49....the Western Germany was used post war until 1990. It's really impossible to say just what they are without seeing a picture. Check the link and see what you can find. Linda C Here is a link that might be useful: Dresdin marks
