B62-395. SLIDE ARM PLOW PLANE. Unhandled, boxwood throughout. The locking thumbscrews don't bear directly on the arms, but instead tighten brass yokes that pull up against the bottom of the arms to lock them. Brass tips on the arms, a brass wear plate on the fence, and a metal plate in the side indicating that it was probably intended as a presentation piece. The plane shown on page 292 of Rosebrook & Fisher. Fine 200-400
