It's very similar to a Rev6.

Nevertheless, not very exciting.. Just a minor revision that didn't live on for very long.
The rev4 has also been spotted in the wild, it was also apparently very short lived. Didn't get good pictures of it from the owner so the evidence isn't archived. As far as I remember, it was closer to rev3 than rev5.
