Cecil Schumacher invented the ball differential in about 1980, and although it said 'Patent Pending' on the parts, he never did get a patent. Cecil was a gearbox engineer, and he used a design from a gear checking machine as the basis for his design. IT is Cecil's original design that has been copied by everyone else. HTH
Yep, I had the XL. That is a very well preserved one, though it's a later one as it has the cut out in the bottom of the chassis near the front. The early ones didn't have that. I've never been able to find a photo of the original stick pack version of the C Car, which is the one I had.
