Small blades are marked “Waterville (curved) Co. Waterbury.” This company began when David Sprague and Alonzo Boyden purchased the old Waterville Manufacturing Company factory from B.H. Morse in Waterbury, Connecticut. They conducted business as Sprague and Boyden until 1871. H.H. Welton became a partner in 1871, and they became Sprague, Boyden and Welton.
Welton left the firm in 1876. The firm was capitalized with $25,000 in 1877, and once again known as Sprague and Boyden. They were sold in 1890 to Sumner Babcock.
