Can you help identify this Limoges France China pattern?

[Moonseeme]

I have been researching on my own and was surprised by the vast number of Limoges china patterns. This set was given to my Grandmother about 30years ago she had gotten it from a friend who also had it for awhile, so I have no idea of its actual age.  Some pieces have R & Co. marked on the back and all have a Blue Swan incased in a blue circle.  I have searched numerous sites and Replacements, LTD but I am not having any luck. Do you know the pattern name or can you point me to other websites where I can continue my research.

Any tidbits would be appreciated.

Is your backstamp the same as this one? Unfortunately I can't get access to see what the piece is like.

There is a piece here being sold on ebay, where the seller is attributing the piece to Raynaud and Co. But I can't find anywhere else thyat suggests this.

Perhaps others will have more luck
