B68-342 SMOOTHING PLANE. Morris "Diamond" Patent. Early version of the design patented in 1870 by Ellis Morris and marketed by Ohio Tool as the "Diamond" plane. This example resembles the plane shown in figure 69 of PTAMPIA II, except that the diamond pattern covers the entire sole and it has "Pat. Apl. For" cast under the tote instead of "1881", and the word "Boss" cast next to the knob. 8" sole, 2" Ohio Tool cutter is original, applewood tote, knob, infill and wedge with wear but no damage, noting that the end of the tote is rounded over. From the collection of Harold Unruh. Good 300-600
