I'm not a clockwork fan.
I just have one, use them as a lever extender.
Pretty common on Oranges at the time, you see old bike crop up with them. (not so much the ram rods.).
Just clockworks are bikes people dump at the tip since they're old, 'cheap' at the time and a bit naff.
But they were only around for a few years and most bikes will have been dumped way before now.
