12-size fullplate plate movement ready to be ‘scaped and finished, the pillar plate stamped GH, its Liverpool size and with 5 small batch marks. Complete with all the train to the contrate including an uncut fusee, the arbors left long for finishing in the English manner. 38.5 mm diameter. Together with its wood veneer pill box.
GH, possibly the stamp of George Holmes in Rainhill, who is shown as working as a “watch movement maker” in the 1841 and 1851 cencuses.
NB: English watch manufacturing was split into at least forty separate specialist trades at this time, around 50% who were involved in the manufacture of rough movements, which the Swiss/French called an ebauche. It is easy to see how much work was still needed at this point, but also to see how wonderfully good and crisp was the work of these pre-eminent, mostly Prescot based specialists.
All rough movement are rare survivors, this relatively early verge caliper even more so. In good dull and dusty condition, the plates still showing the hand scraped decoration that was intended to attract the eye of the finishers.
