B66-352 JACK PLANE. The Challenge. The Challenge plane was patented in 1883 and 1884 by Arthur Goldsborough of Washington, DC (even in the nineteenth century the source of some really bad ideas), manufactured by Iver Johnson, and sold (briefly) by Tower & Lyon. See PTAMPIA I, page 166. This is the 15" jack plane version with the word "Challenge" and the patent dates cast into the yoke. Japanning 90%, wood and metal otherwise very clean. A very nice example of a very rare plane. Fine 1000-2000
