Today we present an article on “Christie Motor Carriages” from the March – April 1922 issue of Amy Ordnance magazine. Written by H. E. Pengilly, the article looks at some of the early designs created by famous tank designer Walter J. Christie. Christie is most well known for being the first designer to create armored vehicles with independently sprung suspensions, giving them very high mobility for their era. Christie was also fixated with convertible tracks, vehicles that could operate both with and without tracks. The motor carriages in this article are examples of some of his early “convertible” designs.
