External rudder control actuator from a German V-2 (A4) rocket, circa 1942-1945, measuring 8″ x 5.5″ x 6″ plus attached cables, featuring an electric motor attached to a central drive sprocket. The sprocket rotates to drive a chain—not unlike that of a motorcycle—to control the external air-rudder vanes. Part of the casing is marked "707/78735," with a Reichsadler military eagle stamp below.
