Don,
This is not an argument re the allocated speeds for the generic Morris 15cwt.
This is more of an interest aspect for me for some other project.
I am trying to find the road speeds of the following Morris-Commercial vehicles.
CS8 4x2
C4 4x2
C8 4x4
C8 Quad FAT
PU8 4x2 according one source had a max road speed of 50mph.
Ref:

And via the all knowing Wikipedia the Morris Commercial (Field Artillery Tractor) had a maximum road speed of 50 mph.
I am assuming this was heavily reduced when towing the 25 pdr gun and limber, thought I am not sure what the DOD speed for towing was.
If you happen to have this speed data could you forward it across to me, either here in forum or PM or email.
Thanks
