B66-662 SMOOTHING PLANE. Birdsill Holly Patent. Holly received his patent in 1852 for the first commercially successful metallic plane. This 9" plane with a smooth sole (the dimpled soles would come later) is unmarked but virtually identical to that shown on page 18 of PTAMPIA II. The tote has a chip from the top, is loose in its dovetailed slot, and has a reglued crack and paper shim at the base. 2" Casey Kitchel cutter. From the collection of Harold Unruh. Good 200-400
