Not a comment about the guns, but the first picture shows well how closely the bodies on the Canadian prototypes matched these Morrises.
Goes to reinforce what an amazing job was done by the joint design teams in Canada to adapt GM and Ford vehicles.

The pic is titled 18 pounder. Would that be a clue?

Query
I know nothing about guns but 18-pounders makes sense judging by the pre-war Canadian papers relating to the 1937-8 Ford-Scammell and Chevrolet-Scammell tractors. The drawings for the bodies were supplied to Ottawa from the Royal Arsenal in Woolwich so this explains why they are so alike.
As it turned-out the 6-wheeler gun tractor was destined not to proceed and by 1939 the 4x4 tractor was the preferred option.

Gun, QF, 18-pdr Mk.1(P).
ie, a WW1 era Mk.1 18-pdr, 'pneumaticised' by convesion to pneumatic wheel/tyre combinations with high-speed axle with ball-type wheel bearings. A salient feature is the single pole-trail. Mike C

correction: cone-and-roller type wheel bearings.
QF is Quick Firing: ie the means of obturation is the expansion of the brass shell case against the breech. Ammunition was fixed type. Gun had a comparatively low range of the angle of fire (+/_ horizontal): quite a contrast to its replacement, the 25-pdr 'gun-howitzer', which was much more versatile. Mike C

Pole trail limits elevation - hence reduces the range! Nice pics of Martin Parry conversion.
