Overlapping its wagon, which has had to be extended on the left, this lathe for turning naval gun-barrels was manufactured by Dean, Smith and Grace Ltd during the First World War.

The photograph, by Hall and Siggers of Keighley, was supplied by Mr Balderson of Moorview Way, Skipton, whose grandfather John Balderson worked on the railways and stands in the foreground.

Engine and machine-tool makers Dean, Smith and Grace concentrated on lathes after 1906, but also manufactured breech-blocks during the First World War, a period when Keighley industries diversified to meet war demands.

Laundry machine manufacturers geared their plants to the production of field kitchens and disinfectors, whilst the Keighley Gas and Oil Engine Company gained the distinction of powering the searchlight that located the first German Zeppelin shot down over England. Between 1915 and the Armistice, a Keighley National Shell Factory turned out 714,000 high explosive shells.
