All selections are recorded on the selector unit assembly:

After pushing one of the selection buttons, the corresponding selector lever A on the selector unit will be pushed outward. Please notice the carriage assembly B , it will become more important later on.

The selection lever now also closes the circuit to the magazine motor A, which starts to rotate.
At the same time this picture shows the relative position of the magazine B, and selector unit C.

The magazine motor will keep on running, until the carriage assembly hits a selection lever. The magazine will rotate from record selection 119 to 1 (odds, main titles).

Than it reverses, and goes through no’s 2 to 120 (evens, or flip sides), and back again.

Once coming on the end of a full circle, a reversing switch A will be activated by trip brackets B.
This will change the direction of the current through the motor, and causes magazine to rotate in the opposite direction.
