Wilcox Silver Plate Company began in Meriden, Connecticut, in 1865 as the Wilcox Britannia Company. It adopted the Silver Plate name in 1867 and acquired the hollowware manufacturer Parker & Casper in 1869. The company made plated table and serving wares, including cruet stands, tea services and ornamental vessels. It maintained New York salesrooms as well as its Connecticut factory.
Wilcox became one of the constituent companies of International Silver in 1898. Its name remained in use under the larger concern, so a Wilcox stamp does not by itself place an object before the merger. Production from Middletown Silver Plate transferred to Wilcox in 1899, and the related Superior Silver name also appears on wares made there. A half-circle Wilcox mark was introduced in 1921 and registered in 1923.
The Meriden factory closed in 1941 during wartime metal shortages. After the war, other International Silver factories made Wilcox designs. About 1961, Wilcox and E. G. Webster & Son were consolidated into Webster-Wilcox. The later combined name belongs to that successor line; earlier crossed-hammer and Wilcox-only marks identify different phases of the business.
Also known as: Wilcox Britannia Company · Wilcox S.P. Co. · Wilcox Silver Plate Company
Both operated in Meriden and later joined International Silver. Read the company name around the emblem; MERIDEN BRITANNIA is distinct from WILCOX SILVER PLATE.
The combined Webster-Wilcox wording identifies the successor line established about 1961, rather than an early Wilcox-only stamp.
