B65-454 BEVEL AND FRAMING SQUARE. G.A. Topp & Co. Patented in 1892 by Thomas Cook and manufactured by the Topp company of Indianapolis, with whose name it is most commonly identified. This is the earlier version and, unlike most examples, is in pristine condition, with the cherry handle perfect and the printed steel handle free of corrosion and completely legible. Far and away the nicest example we've ever seen. From the collection of Steve Dice. Fine 200-400
