Dent London 1882 Clock for Repair

Dent London 1882 No.042

Back of the clock

With the steel balls in place

This is a very unique and rare clock. I searched the internet high and low but can't find any information about it accept a couple of video clips (1 | 2) at YouTube which were not in working condition. This clock was brought to me since it's not working when the owner bought it. It is repaired and serviced and now it's in working condition. Below is a shaky video shot I took after repairing to show how this unusual clock works.
