B67-639 JEWELER'S DRILL. Whitney Patent IOB. Tower & Lyon advertised these drills as the Whitney patent, but the patent date given is actually for a method of making drill bits. The drills are highly prized for their elaborate red and gold pinstriping, which on this example is 85% complete. In its original wooden box, with nearly intact label in the lid. There are two bits included in the wooden bit holder, and in addition a plastic bag filled with bits, at least some of which may be original, and a wooden tube with lengths of wire. We're not sure if it came with the drill, but it was included in the box so the buyer gets it. Good+ 300-600
