B66-451 BEVEL GAUGE. Skinner Patent. Patented in 1874 in William Skinner of Milford, MI; it consists of a brass gauge designed to be screwed to a bevel so that the blade can be set to a precise angle. It was marketed by the "Quadrant & Novelty Works" of Milford and was a resounding flop; first one we've seen. Marked with the patent date; the brass is oxidized but otherwise in immaculate condition. From the collection of Steve Dice. Fine 100-200
