The Foundling Museum has an incredible collection of old clocks, some dating back to the 1700's. Clocks like these require the skills of some pretty special people to maintain and repair them. These experts are from West Dean with decades of experience between them.
The clock being taken apart here is an 1850's mahogany table clock with a silver dial signed by J R Losada of Regent St. (Clocks of this era would usually have the name of the retailer on them).
It needed a fine tune to ensure its strike was regular and perfect. Dust and heat can cause problems. However this one should be fine for several more years after being put back together.
