B58-635 COMBINATION BRACE DRILL. Quimby Backus No. 2. Incorporating Backus? own 1880 chuck patent and Seymour Bostwick?s patent for the brace/drill combination. Produced as part of Backus? ongoing wars with the Millers Falls Company. Unmarked (or the marks have been worn off by cleaning) but the design is unmistakable. There's a small crack in the chuck and the ratchet needs some work. From the Cecil Holmes collection. Good 100-200
