Lucas magnetic sensor

[Stowe, Ted-SEA]

both of these distributors are from mgb's, the optical one is from a 76, the
other is somewhere earlier. the trigger wheel is a flat wheel with 4 tabs,
the emitter and receiver are set up where the points would be, 3 wires leave
the sensor/emitter setup, which went to an amp which was mounted on the
inside of the left fender.

What is the distributor from?  If it from a Lucas OPUS (Jaguar V12 1971-80,
or MGB V8 or a few others) then the trigger is a high frequency balanced
transformer.

If it is OPUS, you have very little chance of making it work with any other
form of ignition system.

What does the trigger wheel look like?

What cars were these fitted to?
