The International Silver Co. Wilcox 5698 mark indicates that this piece was produced by Wilcox Silver Plate Co., a division of the International Silver Company. Wilcox was known for crafting elegant and sturdy silverplate hollowware, and the 5698 is a specific design or catalog number. This kind of marking is typically found on decorative or service items such as trays, bowls, or teapots made in the early to mid-20th century. The presence of both names reflects the merging of historic silversmith firms under the International Silver umbrella.
