The Italian M13/40 Medium Tank attempted to rectify one of the principal problems with the M11/39, that the 37mm Main Gun was fixed in the hull with a limited traverse of just 15° to port or starboard, by using a similar hull and a new 47mm main gun mounted in a revised turret.
Despite a slight increase in armour thickness, the vehicles were prone to brew up when struck by the British Army’s tanks during the North African Campaign of WW2 and most were simply abandoned by Italian Crews.
