Here are the Canadian '33-'34 V-8 numbers from their Archives. I forgot that there is letter between the 18 and 'F' in their sequence of numbers for V-8s which were in blocks of 5,000 numbers (the 'F' only used for those engines destined for RHD chassis).

1933 model V-8s: C18H 1 to 5000, C18N 1 to 5000, and C18X 1 to end of model
run which was less than 5000

1934 model V-8s: C18A 1 to 5000, and C18E, C18G, C18K, C18L, C18M, C18P, C18S,
C18T, and C18X all in blocks of 5,000 engine numbers except C18X which ran to the end of the model run and was less than 5000.

For RHD vehicles, an 'F' was added to the prefix (e.g. C18HF).

As the original subject is Australia, only the V-8s carried Canadian engine numbers while the fours came from Ford of Britain which used the U.S. numbering system (assigned to Dagenham in blocks of numbers by Dearborn).

Speaking of built-in-Canada '33s, unlike in the U.S., body-colored fenders, fender aprons, gas tank cover, and spare tire cover was an inexpensive production option available for their passenger cars. Too bad that option wasn't available in the U.S. as some wish.
