According to the link below the 75mm M18 shell belongs to the French Designed, American build 75mm M1897A gun. The Artillery Regiments of the 2nd Canadian Infantry Regiments were at first equipped with these types of guns in England, in 1940. However I don’t think that these shells were for the 2nd Division guns.
The 75mm M1897A guns were also mounted on halftracks to make the 75mm Gun Motor Carriage M3. These were widely used by the Americans, and some were supplied to the British. The RCDs in Italy had used a small number of these SP guns also.
