Vintage Griswold Manufacturing Co. Cast iron 3-burner gas stove top section, marked “GRIS 2030 WDLT” and made in Erie, Pennsylvania. Griswold was one of the most respected American manufacturers of cast iron cookware and commercial kitchen equipment in the late 1800s through mid-1900s. Pieces like this were built for restaurants, boarding houses, and industrial kitchens, designed to run daily for decades – and many still survive today because of that build quality. This unit is a great example of that era: Heavy cast iron construction, simple mechanical gas valves, and a design focused purely on durability and function. It carries the kind of industrial character that modern equipment just doesn’t have. One corner crack (see photos). Great for restoration, parts, or industrial decor.
