Lang, if you are referring to the pictures on page 1 of this thread I agree. But other trucks and armoured cars (and weaponry) from NEI sources were found in various parts of New Guinea and New Britain. See for instance here:

The only doubt I have is with the last pic on that page.
Any comments apreciated,
Kind regards,
