horological file

Horological crossing-out file by unknown maker, England, 1850-1900

Crossing-out files are used to shape the inner cross-section of a gear wheel or similar component in a watch movement.

This tool was collected from the workshop of Richard Oliver (1904-89), a watch-case maker based in Clerkenwell, London. Richard was the fourth generation of his family to be apprenticed as a watch-case maker when he joined the family business at 31 Wynyatt Street, Clerkenwell, in 1920. In 1941 the business moved to a larger workshop at 25 Spencer Street, Clerkenwell, and Richard took over from his father in 1949. In 1971 the workshop in Clerkenwell was closed and the contents partly sold to Liverpool City Museum and the remainder moved to Richard’s home in Woodford Green where he continued to work. From 1971 onwards the Oliver family gathered together a unique collection of tools and equipment including the contents of the case-making workshops of J. Walton and F. Thoms, previous occupiers of Spencer Street.
