Unfortunately the production data I have prior to 1975 appears to be for the US only, as the first reference I have to the Corolla starts with January of 1968 and frame number KE10-232314. Most of that information is available at Stepho's Toyota Site if you'd like to check it out.
I get the impression that if Toyota kept more detailed records of this sort of thing (especially importation dates, etc.) and retained it, the data is buried in paper records at the back of some musty archive vault in Aichi or Tokyo.
