c. 1920s/1930s; Colebrookdale Iron Co. – Boyertown, PA, U.S.A.
Complete Keystone No. 20 clamp-on food chopper housed in its original printed cardboard box, marked “Registered U.S. Patent Office” and manufactured by Colebrookdale Iron Co., Boyertown, Pennsylvania. The box retains bold Keystone trade mark graphics, Good Housekeeping Institute approval seal, and illustrated parts diagram with numbered components and ordering instructions. Inside, the grinder body is clearly cast “Keystone” with raised “20” at the throat and “Colebrookdale” along the frame. Included are the original wooden-handled crank, auger screw, multiple perforated plates (varying grind sizes), cutting blade, retaining ring, and mounting hardware.
Chopper components show light oxidation and surface wear consistent with age. The original cardboard box exhibits heavy edge wear, tearing, creasing, and loss at the lid corners, but remains structurally present with legible graphics and text.
Box: 9.25" W x 3.5" D x 4" H
