This is the second machine that I purchased. It was rusted solid, so it required repainting. I need several parts to make it complete, the thread tension, shuttle and bobbin as well as the treadle. I have the silde plates but did not have them in place when I took these pictures. Maybe some day I will find enough pieces to make it complete. Elias Howe Jr. had the first US Patent for a viable sewing machine in 1846. This machine was manufactured by the Stockwell brothers, the sons-in-law of Elias, after he and his brother Amasa B. Howe desolved there partnership about 1864/65. The Stockwell brothers machines are distinguishable from the A.B. Howe machines in that their machines have a brass medallion of the bust of Elias Howe Jr. About 1873 Amasa's son B.P. Howe sold his fathers business to the Stockwell brothers. They remained in business until 1886. The last patent date on the slide plate of this machine is Jan, 30 1872 with a serial number of 921,069 so I believe this machine was manufactured sometime around 1876 to 1877. There aren't many records available, that I have found, to date these machines.
