Comparing: Renault FT 75 BS vs. T1 HMC

The first order for an SPG on the basis of the Renault FT-17 was placed in December 1917. However, no SPG entered service until the end of World War I. After the end of the war a total of 39 vehicles were manufactured.

The T1 Howitzer Motor Carriage was created in the fall of 1930 on the T2 chassis. The design incorporated components of the T1 Cunningham. Due to the Great Depression, all work on the project was discontinued at the prototype stage.
