This was the first of two production prototypes, A13E1 being the original Christie vehicle
This was the first British tank to use Christie suspension and followed recommendations
from the Assistant Director of Mechanisation at the War Office, Lt. Col. G.
Le Q. Martel who had been impressed by Christie prototypes he had seen in trials.
A prottype Christie vehicle was purchased (A13E1), from which the eventual design
evolved. There were two production prototype vehicles, A13E2 and A13E3. The
vehicle took just two years from allocation of funds in 1936 to delivery in
January 1938. They were used by the 1st Armoured Division in France, 1940 and
in small numbers in Libya, 1940 - 41.
