Electroplated bowl with stamps

<Hi, this bowl looks to me electoplated. The handles are wooden and the bowl is from France but it is not necessary where it originated. I would like to know what the stamps at the bottom say. Thank you for your help.><><>

It is French electroplate. French electroplaters’ marks are conventionally in square surrounds so here DR identifies the manufacturer. 15G[rammes] is the amount of silver used in the plating process.


Thank you for your help, Phil. Thanks to your answer I look into it futher and DR might by stamp of French silverplated makers Durousseau & Raynaud from Lyon.
