The Auburn Tool Company began making moulding planes in 1821. The company contracted prison labourers, who were incarcerated in nearby Auburn Prison, in New York state.
This contract was in place until 1864, when the company was bought by The Ohio Tool Company. These prison made planes were considered to be of very high quality. The plane pictured above was made in Auburn Prison. It is a 2 inch "hollow" bottom plane. This plane is in excellent condition, and though it is about 150 years old, it can still be used today. The company name is embossed on the front of the plane.
This plane, and many others can be purchased at The Waterford Antique Market.
