Parts & material for Congreve clock

Parts and material for a Congreve rolling ball clock to John Wilding's design. The table has been built, there's a largely finished spring barrel and a mainspring to go therein. Rest of the material is mainly brass, wheels and chapter ring blanks.

You probably know what a Congreve clock looks like and how it works - if not there's a short clip of my own clock here. I've got quite a lot of clocks and, suffice to say, few look as spectacular when working or are as downright difficult to adjust, maintain and keep working as this one. Consider yourself warned!
