George Ridout, trained in London, frequently used the English custom of striking the maker's mark four times. Other works marked in this fashion include a salver, circa 1750-65 and a pair of sweetmeat dishes, circa 1745-55 (see K. Buhler and G. Hood, American Silver: Garvan and other Collections in the Yale University Art Gallery, 1970, vol. II, figs. 695 and 696, pp. 122 - 125).
