The Christie M1931 originated as the M1928, which used Christie's suspension, and had the ability to run on its tracks or the wheels.The M1928 was demonstrated unofficially to the US Army by traversing a route at an average speed of 45 km/h (28 mph); by contrast the US Army's T1E1 tanks – expected to replace their WWI-era M1917 light tanks – averaged 16 km/h (9.9 mph) over the same route.
The US Tank Corps ordered a single tank from Christie's company based on this design. The tank, known as the M1919, was delivered in early 1921 and tested until Christie proposed modifying it. The modifications added coil suspension to the front wheels and removed the turret - the armament being moved to the nose of the vehicle.
