Barbour Silver Company quadruple silver bowl. Guessing it is from around 1912. Quadruple silver plating differs from standard: standard silver plating is 0.0003 inches thick; quadruple plate silver, as the name implies, is four times as thick: 0.0012 inches. Freshly polished, this is a beautiful addition.
Barbour silver operated under that name from about 1896 to 1931.
