Motor Scout was the first armed petrol engine powered vehicle ever built. It was not intended for running over ploughed fields or charging but designed to provide a cover or support infantry and cavalry wherever good roads were available.
It was designed and built by British inventor F R Simms in 1898. He mounted a standard mark IV Maxim machine gun above the front wheels of a quadricycle. The Maxim gun took, with its readily accessed 1,000 rounds of ammunition, the place of a second rider. The driver operated the machine gun. He put an iron shield in front of the car for the driver's protection.
A one and a half horsepower Simms' Patent Automatic Petrol Motor with Simms magneto-electric ignition was fitted and the standard tank carried enough fuel for 120 miles. The Motor Scout was convertible to a two-seated quadricycle. The quadricycle was also available without the gun for non-military purposes as a two-seated vehicle for £120.
