Cruiser Mk VII, A 24, Cavalier, prototype:
Great Britain's Cruiser Mk VII, A24, Cavalier
RAC Tank Museum


Nuffield designed a replacement for the Crusaders. These were going to be the Cromwell, however not enough of the new engines were available so Liberty engines were installed. The War Office ordered 500 before it had undergone trials.

The design was rushed and problems were encountered.

Very rectangular hull and a roomy but angular turret.


The co-driver operated the hull machine gun.
