There is a fascinating article in the latest edition of Antiquarian Horology, just starting to arrive through people’s letterboxes, setting out a remarkable research question which cries out for some crowdsourcing of data—hence this blog post. For those who don’t receive a physical journal, the editor has conveniently made it the sample article for this quarter. You can download it here.
The article updates and highlights an observation made forty years ago, that there are a host of common features observable on a range of late seventeenth and early eighteenth-century English clocks which, taken all together, suggest the movements may have originated from the same manufactory, despite being signed by a range of well-known makers.
Put simply, it is suggested a range of prominent makers (or perhaps retailers) bought in largely finished movements from a single source, and arranged for their casing/signature/final finishing.
This is clearly a very well-understood practice in the watch world from a relatively early date, and was certainly common practice in the clock world later on. For example, Thwaites produced movements for a wide range of other clockmakers and clockmaking firms, and on a large scale. The question remains, how early did this standard practice emerge, and is there sufficient physical evidence to allow us to draw firm conclusions?
Jon Parker has collaborated with a restorer and collector who have in turn spent decades documenting the evidence, identifying what they argue are a clearly observable set of designs for clock parts which are highly characteristic and suggestive of a common source. Jon has assembled an article that walks the reader through all these features, with clear illustrations of examples, allowing the reader to make comparisons with any clocks to which they have access. The features range from highly stylised features on the hour and minute hands, to details of hammer heads, and particular shapes of the lobes on back-cocks or hour bridges, or patterning such as the rings on set-up ratchets or count wheels, or the form of click-springs, and much more besides.
The key element is that Jon’s piece is a call to arms! More data is needed. And it is not difficult to look for it. This is a massively worthwhile project to support, and whatever the outcome, if you can supply data you can play a part in improving our understanding of clockmaking practice in London in the period 1660–1720.
