Help please with marks

Hello, would anyone recognise these marks please. Are they silver or plate?
Thank you for any assistance

It’s a French electroplate mark. The manufacturer is Société des Couverts Dixi. 42 is the amount (in grams) of pure silver used for plating the full set (normally 12 pieces).

Thank you Phil, that’s great to know.
