Revell Austrailans and ESCI 8th Army are fully compatible and interchangeable IMHO. The heads I mean, because the Revell's product accurately depicts the peculiar Australian jackets, not applicable to the British and NZ units.
The size is just the same so don't hesitate to mix them up.

I'm one of those nerds who get one of the sets in order to keep it "MIB on sprue"
Thus - if you mean the Call To Arms set, there's a photo available on PSR. Early days when he intended to paint everything up.

Please, feel free to pose the questions since there're many more boxes on my unfortunate shelves...
