B66-603 UNHANDLED SCREW-ARM PLOW. J. Kellogg. Body, fence and wedge are a dark rosewood; boxwood arms, nuts and shoulders. A couple of very small chips in the threads and typical light wear on wedge, otherwise immaculate. One interesting feature that we haven't seen is that the screw that adjusts the depth gauge has notches, and there is a lever that locks it at various depths. Possibly a user modification, but looks original. B mark. An unusual and exceptionally attractive plow. From the collection of David Jeffers. Fine 150-300
