B67-604 IVORY-TIPPED SCREW ARM PLOW PLANE. Unmarked Sandusky No. 129. Left unmarked for resale by a dealer but unmistakable. Applewood with boxwood nuts and arms and boxed fence. Nickel plated fittings, early type ivory tips with small knobs. Sandusky cutter. The wood is nearly flawless, noting a couple of small checks in the fence and user names, the ivory is lightly yellowed with a couple of cracks, and there's a little surface corrosion on the metal parts, but overall one of the nicest examples we've ever seen. From the collection of David Jeffers. Fine 350-700
