Redon Limoges Porcelain

Have you heard of Redon Limoges Porcelain? 

No neither had I until I climbed up on the kitchen steps to clean a shelf and had a good look at some items which were left to me by my grandmother when she passed away in 1987.

This is a scanned-in pic as no camera at the moment

I looked it up on the internet and found this site:

(see below) 

and according to the green hallmark the pieces were made between 1891 and 1896, so are well over 100 years old.  Not surprisingly it is no longer a set, being four plates, three saucers, two cups and a cream jug.  
However, I can't find anything similar on the internet, not on eBay or any of the china-finders sites.  It would be interesting to know what they're worth, although I love them so am not ready to part with them yet and it would be nice to add to the set.

Redon Limoges Porcelains     R30

Martial Redon and P.J. Gibus became partners in a Limoges porcelain factory c1861. Redon became the sole owner when Gibus retired in 1881. In 1886 Redon exhibited plates, cups, and vases with lavish decoration; the company also did underglaze patterns and pate-sur-pate. Later Redon was known for more utilitarian pieces. 

Martial Redon's son Joseph became a partner shortly before his father retired in 1896. P. Jouhanneaud and his son joined with Joseph Redon in 1906, and the firm became La Porcelaine Limousine (P55). P. Jouhanneaud's nephew, George Magne, became a partner in 1912 and took over the company in 1918. The factory closed in 1938.   Alexandre Chastagnac repaired and reopened the factory in 1945-46, then built a new factory nearby in 1955.
