B65-100 EXTENDIBLE BREAST DRILL. Rusby Patent. Earliest version of Rusby's gizmoish extendable drill with the integral cast iron handle, far less common than the later version with the wooden handle. Marked with Rusby's 1903 patent (first of three). The small breast plate is missing as usual and we're not sure the first version had one. Some of these drills had decorative red and gold highlighting, this one has solid black japanning which is complete. From the collection of Jim and Christa Schoenky. Good+ 100-200
