Herllo, rather think - in view of the yellowish colour - of unplated German Silver (Alfenide, Metal Blanc) than electroplated. This pattern was produced in several countriea, a French influence (i.e. Christofle) is certainly a possibility. Have been unable to identify the mark, believe this to be a retailer*s mark rather than a maker's mark - just a gut feeling, though. Regards Bahner
