Brand Names: Keystone Food Chopper

Primarily known for food grinders, vintage ca. 1920s-1940s. Hollow ware produced as sideline to promote grinders appears to be limited to a #5 skillet. Skillet is of smooth bottom design, which would correspond to timeframe of food grinders.

Food grinders are marked "C.I. Co. Boyertown PA", the C.I. appearing to stand for Colebrookdale Iron, a company originally engaged in the manufacture of sad irons and trivets, with history as far back as the early 1700s. Early 20th century advertising copy confirms this.
