B63-104. PULL CHAIN DRILL. Hjorth Patent. Patented 6/11/95 by Henrick Hjorth of Boston and sold as the "Auto" hand drill by Best Tool Co. Powered by pulling a spring-operated knob on the side. 9" long, very clean and works smoothly, although the original leather strap looks brittle so we haven't yanked on it too hard. This is the version shown in the patent drawings, the chuck is just a hollow tube locked with a setscrew. Marked only with the patent information. Lot 107 is the later version with the manufacturer marked. Good+ 150-300
