ANTIQUE VICTORIAN SILVER PLATE SUGAR NIP TONGS 11 cm 24.2 gms "J W & S" INITIALS

A mark that reads "J W & S" on a piece of silver likely indicates that it is silver-plated, not solid silver, and is a maker's or sponsor's mark rather than a legal hallmark. To identify the specific maker, you'll need to search a database of historical maker's marks, such as the one found on Silver Makers Marks, to cross-reference the initials with a manufacturer's name, such as the Joseph Willmore, John Yapp, and John Woodward partnership which used "J W & S" initials between 1834 and 1839, according to a history on Silver Makers Marks.
