The Dooling Bros. number 3 Mercury car presented here is outfitted with a tiny engine complete with a Champion Spark Plug, as the side decal attests. In well-preserved, beautiful condition, it is ideal for display, or racing. Also included is a Dooling Bros. Prototype race car, currently not equipped with an engine. A beautiful example with leather upholstery and a detailed, engine turned instrument panel, this is a fine display piece and would make a fine racer when reunited with the necessary internal components.
