Hub Light, Steering Encoder Wheel

This is the toothed sprocket used in many driving games such as Sprint, Sprint 1, Sprint 2, Sprint 8, etc.

It should be the same as the large trackball used in Football and other games which is numbered 000616-01 but I am not certain until I dig out a trackball and compare - the differences (if any) would be minor in any case and easily modified to suit. Chances are these are the later 000616-01, however the box number didn't say that, so I can't ensure they are the -01 variation.
