Brians friend's friend's clock

The ironic thing I find of mass produced clocks is that you never see the same one twice. Of all the variations I see there are very few benefits or improvements in design. Like the quick release mainspring barrels. There are several ways of approaching the quick release after removing the click ratchet. The self regulating of the hour with its chime - the fourth quarter, has many approaches but none seem better, cheaper or easier to produce or work on than the other.
