B66-659 SMOOTHING PLANE. Bailey Split Frame. An example of Series D of Leonard Bailey's initial foray into plane manufacturing, made after he relocated to Boston in 1858. It closely resembles the plane shown in Figure 13b of the biography by Paul Van Pernis and John Wells, except that instead of the knob being screwed onto a threaded rod, it is held by a flat head machine screw screwed into the boss - unusual but not unheard of. The paddle-shaped adjustment screw is cast iron rather than brass, which may be unique, and tends to rub against the knob. 8-7/16" sole and 1-1/4" original Buck Bros. iron, chip breaker may be a replacement. Wood clean, japanning nearly intact. The rod that the upper section pivots on, which was peened at the ends, is loose but present. From the collection of Harold Unruh. Good 3000-6000
