- Source: Davidson-Duryea gun carriage
The Davidson-Duryea gun carriage was originally a 3 wheel armed vehicle built by the Duryea Motor Wagon Company in the 1899. The gun carriage was ordered by Royal Page Davidson of the Northwestern Military and Naval Academy in Highland Park, Illinois. One Northwestern cadet wrote: "With this gun you could sneak upon an enemy and fire 480 shots and get away before they would know what happened." In 1900 the carriage was modified to 4 wheels and eventually into the Davidson Auto Battery armored car.
