Is the British "C600" a post-war spec, or wartime?
If the Canadian chart specifies North American oils/greases (SAE), then there is a possibility that it could be referring to 600W gear oil, also a high viscosity and sticky oil that was in common use during the 20's and 30's as diff oil for the Model T and A Ford cars and trucks. Many other heavy US (and therefore, probably Canadian, trucks of the era used it for diff oil).
