These lovely sterling silver spoons are in a Colonial Revival pattern, simply decorated with a shell at the tip of the handle. The backs are stamped with the high-end retailer's name "Bigelow, Kennard & Co." of Boston, indicating a date before 1922. The backs of the handles also have a monogram "T" in a style that would point to ca. 1890-1900, and the mark 925/1000 which would also support that date range.
Although the maker is unknown, it is very similar to a number of patterns called "Shell" that were made by virtually all the more important silver manufacturers at the time (Gorham in 1890; Reed & Barton in 1900; Towle in 1889; Frank Smith in 1890; Mt. Vernon in 1865; and Lunt in 1888). It appears most similar to Frank Smith's version, but would work nicely with any of these or other Colonial Revival patterns.
Excellent condition. 8.5" long.
