That is a very helpful response.
AS I said, we don't often see these machines in use.

I would love a photo/video, showing a close-up of the rear
control and the components of the Predicta and its settings.
Most folk - who will never own an Auto - would have no idea how
the system was intended to work.

Perhaps you could help with a video devoted to the Predicta mechanism?

Cheers & thanks
