Barnbow No. 1 (Leeds) National Filling Factory, Tin-smithing and Cylinder Repair shop
c1916-18. Image shows a view of the shop used for the renovating of cartridge cylinders and tins at the Barnbow National Filling Factory during World War One. With an average total of 450,000 of all types of cartridge cases and packing cylinders handled every week, the need for a specialised department to rectify damage sustained in transport or remedy slight deflects was paramount. Initially defective cases had been sent to outside firms for repair but this proved extremely costly, so as soon as the necessary machinery was available a number of women were trained in tinsmithing, turning, buffing and polishing and the expertise they gained enabled the factory to reduce their costs by around a half.
