7101-001 BAYLEY patent core box plane. 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 is actually marked "GIC" which refers to Gray Iron Casting Co., one of Bayley's companies. With each pass of the plane, the cutter rotates slightly. Mechanism a little sloppy but complete. Good 100-200 (RRT1124)
