Because of their brief association, the 1862 prize medal awarded to A. B. Howe was sometimes credited to Elias. The latter did receive awards for his patent, but never for his manufactured machines. When the two brothers dissolved their joint venture, Elias attempted to call his new company the Howe Sewing Machine Co., but Amasa's claim that this name had been his exclusive property for many years was upheld by the courts. Elias then omitted the word "Sewing" and called his company simply the Howe Machine Co. After Elias died in 1867, the company was run by his sons-in-law, the Stockwell brothers. To distinguish their machines from those of A. B. Howe, they marked each machine with a brass medallion picturing the head and flowing locks of Elias Howe. They also continued to advertise their machine as the "original" Howe. In about 1873, B. P. Howe, Amasa's son, sold the Howe Sewing Machine Co. to the Stockwell brothers, who continued to manufacture Howe machines until 1886. The machines of the A. B. Howe Sewing Machine Co. may be dated by serial number approximately as follows: _Serial Number_ _Year_ 1-60 1854 61-113 1855 114-166 1856 167-299 1857 300-478 1858 479-1399 1859 No figures are available for 1860-1870, but 20,051 machines were manufactured in 1871. The machines of the [Elias] Howe Machine Co. are not believed to have begun with serial number 1, and no figures are available for 1865-1867. After that, the machines may be dated by serial number approximately as follows: _Serial Number_ _Year_ 11,000-46,000 1868 46,001-91,843 1869 91,844-167,000 1870 167,001-301,010 1871 301,011-446,010 1872 446,011-536,010 1873 536,011-571,010 1874 571,011-596,010 1875 596,011-705,304 1876 No figures are available for 1877-1886.

(Smithsonian photo 34551.)] Figures 99, 100, and 101.--THE N. HUNT (later, in 1856, Hunt & Webster and finally in 1858 Ladd and Webster) sewing machine was based on the patents of Christopher Hodgkins, November 2, 1852, and May 9, 1854, both of which were assigned to Nehemiah Hunt. First manufactured in 1853, the machine, which closely resembled the Hodgkins' patent, won a silver medal at the exhibition of the Massachusetts Charitable Mechanics Association that same year.
