General Information
Auburn Tool Co. was part of a collective effort between H. Chapin's Son, Greenfield Tool Co. and Sandusky Tool Co. called the Plane Maker's Association, organized circa 1858 to fix prices. Thus, the prices in the pictured catalog pages (from 1869) were agreed upon between the leading plane manufacturers at the time. In 1866, Auburn Tool Co. lost their prison labor contract, outbid by J.M. Easterly & Co. which later became A. Howland & Co. Upon the dissolution of A. Howland Co. in 1874, Auburn Tool Co. resumed the use of prison labor. On November 14th, 1893, they merged with Ohio Tool Company of Columbus, OH. While plane production continued in Auburn, it was under the Ohio Tool Company's name.
