Default slow motion drives?

Has anybody seen inside one of those slow-motion ball drives
that is 6:1 nornally, but 36:1 in reverse for a few revs?

I'm just curious as to how they work inside.

Also, how common was the Eddystone drive arrangement that
used a pinch-wheel as the first reduction ratio?
