B65-369 EXTENDIBLE BREAST DRILL. Rusby Patent. Unusually nice example of the second version of Rusby's gizmoish patent that could be extended to fit into tight corners. Includes the almost always missing detachable breast plate; original wooden handles with a large split in the upper handle, japanning about 50%, works smoothly. From the collection of Jim and Christa Schoenky. Good+ 100-200
