B68-659 JOINTER. The Challenge. Patented by Arthur Goldsborough in 1883 and 1884, manufactured by Iver Johnson and distributed by Tower & Lyon. Unlike the shorter versions which have the word "Challenge" cast into the yoke, this one has "Challenge" and the patent dates cast into the body by the toe. All Challenge planes are very rare, and PTAMPIA concludes that there was only one production run before T&L gave up on them as a bad idea. This one is in decent shape, with 80% japanning and light wear to the black painted tote and knob, light surface corrosion on the cutter and adjustment mechanism. A very rare plane, particularly in the jointer size. From the collection of Harold Unruh. Good 300-600
