The Post Office Electrical Engineers' Journal'', 1937 In 1910, the
meter department of GEC was incorporated separately as Salford Electrical Instruments Ltd, a subsidiary company employing 1,000 workers. Since 1905 the department had been based at Bow Street Works, a small two-storey building at the rear of GEC's large Peel Works on Silk Street. The device was manufactured at the Salford works, and was over 90% successful in disrupting German flying bombs such as the
V-1 and
V-2 in mid-air, significantly reducing civilian casualties. the company relocated to Barton Lane in
Eccles, taking over the four-acre site of the former Jonex Mills. Here, the company produced electrical components such as capacitors, thermostats, telecommunications equipment, rectifiers, and potentiometers.
Decline The Eccles factory closed in the early 1980s. The site was subsequently redeveloped into an industrial estate. On December 22, 1993, the remaining assets were transferred to GEC, and the company ceased to operate independently. In Heywood, local Member of Parliament
Jim Callaghan unsuccessfully appealed to
Lord Weinstock, the managing director of GEC, to retain the factory, saying its closure would result in the loss of 362 jobs. In 1999 GEC merged with British Aerospace to form
BAE Systems, and Salford Electrical Instruments became part of this larger entity. == Products ==
