In 1940 the Montreal Locomotive Works designed a tank based on the turret from an American M3 Lee with a cast steel hull. Some believe this is where the US designers got the idea for the Sherman.
Had a cast hull with the driver on the right in the front.
Machine Gun Turret
There was a machine gun turret on the left side. This had a .3" machine gun and could traverse 120° left and 50° right.
The turret was also cast with the mantlet being bolted on. A few of the vehicles were produced with shoulder controlled 2 pdr guns as the 6 pdr wasn't available.
The Canadians had converted some Priests to be infantry carriers, however, these were too tall so an alternative was needed. The Canadians had used Ram tanks as training vehicles in Britain and were not being used. 500 of them were moved to a Canadian workshop in France code named "Kangaroo." These had the turret and other equipment removed and two bench seats were installed.
Climbing rings were welded on the sides to assist the infantryman in getting into the Kangaroos. The infantrymen's weapons couldn't be used from inside the Kangaroo and there was no overhead protection.
