The 123MID-4-R-V is designed with the Midget-enthusiast in mind. It is available for the old 'pre-Aplus'. A straight distributor cap is fitted. 

The unit is layed out in such a way, that static timing can be done on TDC, by means of the built-in LED.

The 16 curves are nicely divided over the spectrum, so that the unit lends itself perfectly for tuning.

The installion manual also offers a comprehensive list, that links a curve-setting to a particular engine.
