B63-99. RATCHETING BREAST DRILL. International Mfg. Co. Very uncommon breast drill, instead of a crank it has an extendable arm that works like a pump handle. Japanning about 75%, good mahogany handle and rosewood head, working Barber-style chuck. Like every one we've seen, it's marked with the Worcester, Mass, manufacturer and "Patent Pending." Good+ 100-200
