Hall Scott was the company that employed the designer and builder of the model T accessory Ruckstell rearend, Grover Ruckstell

Grover Ruckstell earned his master degree in automotive engineering from Princeton University. He later became well known in the racing circles as head of the famous Mercer racing team. In 1914 Ruckstell and Eddie Pullen both drove Mercers in the famous Corona Road Race at Corona, California. The race track was a perfect three mile circle which still exists today as Grand Avenue. The competition was fierce with such drivers as Bob Burman, Eddie Rickenbacker, Earl Cooper, Ralph DePalma, and Barney Oldfield.

Ruckstell’s involvement with the two speed rear axle is reported to have begun in 1913 while he was working for the Ford Garage in Maricopa, California. The first axle he built was for a truck used in the local oil fields. This interest was cut short by World War I when Ruckstell joined the new Army Air Force and was commissioned a Captain.

Following the war, Ruckstell was employed by Hall Scott Motor Works, Berkley, California and became head of the Airplane Motor Department. While employed there his interest in the two speed rear axle was renewed.

Ruckstell was not the inventor of the two speed rear axle. However, he was the most successful entrepreneur who succeeded in developing the basic concept into a popular product.
