Yes, Hanno: Ford Motor Company of Australia stamped the original engine number onto the chassis for all models, including CMPs assembled in Australia (but not individual CMP trucks imported from Canada as CKD - they retained their usual CDN method of ID, such as the engine number stamped onto the edge of the gearbox/bell housing).
The usual place was adjacent to the engine cross member on the RHS, on the horizontal part of the chassis rail, but Keith has also seen the number stamped onto the vertical, as mentioned above. Hence, the chassis stamping could only be done at the point where the chassis was on the assembly line and the engine/transmission was assembled onto the chassis, ie at the point of 'mating' of these components.
I don't know if any other Commonwealth countries with Ford assembly lines stamped the number is similar fashion, but it was certainly the case in Oz where a sizable amount of the truck was locally manufactured, not imported.
