The International Silver Co. Webster Wilcox 177 mark reflects the merger of the Webster Company and Wilcox Silver Plate Co., both of which were absorbed into the International Silver Company. This particular mark, including the number 177, identifies a specific pattern or model—often associated with formal silverplate service pieces like trays, tea sets, or serving bowls. Webster Wilcox pieces are known for their clean lines and heavy plating, making them a favorite in both domestic and hotel silver settings during the mid-20th century.
