Based in Cleveland, Ohio, A.G. Mason Sewing Machine Company manufactured sewing machines from the 1880s to about 1916. After the original Florence Sewing Machine Company went bankrupt in the late 1870s, Mr Mason apparently acquired the company in the early to mid 1880s. This new company, doing business as the Florence Machine Company and located in Florence, Massachusetts, manufactured sewing machines based on White models.
Like many of the smaller manufacturers, A.G. Mason seems to have concentrated on making sewing machines for department stores and other retailers. Models sold by the company included the Defender, Wilson, Crown, Queen, New Queen and Florence. In the early 1900s, the company apparently moved its operation to Cleveland, Ohio, and was renamed the A.G. Mason sewing Machine Company. In 1916, the company was purchased by the Domestic Sewing Machine Company which itself later merged with the White SM Co. in the 1920s
