Hi Dean,
Akiba had a reduction belt drive based on a Hacker C-50 at the Japanese Championships. Not a contra but it may have been confused for one. Follow the link for photos and details.

Hello Brian / Serious Power
Did I read correctly? Did you suggest that you've seen a belt-drive contra-rotator?
Details, please!
Best Regards,
Dean Pappas
