B68-347 CORE BOX PLANE. Bayley. Actually patented by John McCauley?of Springfield, OH, these very gizmoish planes were manufactured by Wm Bayley of Springfield and are usually referred to by his name. This example has "Wm. Bayley Co." and "Springfield O" cast into the arms. With each pass of the plane, the cutter rotates slightly. Clean and works smoothly. There's a knob mounted on the left arm that we haven't seen before and could be a user modification. From the collection of Jim and Becky Leamy. Good 120-240
