B66-541 NUMBER ONE SIZE PLANE. Chaplin Patent No. 0. Smallest and by far the rarest of the planes based on Orril Chaplin's 1872 patent manufactured by Iver Johnson, and described as a "model maker's plane." See catalog reproduced in PTAMPIA II, Figure 243. 5" sole, 1-1/8" unmarked cutter. The cutter support (which Chaplin called the "saddle") is brass rather than the customary cast iron, and the cutter itself appears to be a replacement. Nickel on lever cap is worn, and only traces remain of the red japanning on the bed. Still an incredibly rare plane, with only two others known it will be a long time before you see another. From the collection of Harold Unruh. Good 6000-12000
