Walter T Glover established his wire manufacturing company in 1868, occupying premises at the Bridgewater Street Iron Works in Salford. W T Glover & Co, known as Glover’s, originally made cotton-covered and braided, insulated copper wires for use on bell, signalling and telephone circuits. As trade developed, the company moved to the Springfield Lane Cable Works in 1880. At this time, factories and larger private homes were beginning to install electric lighting, which required better insulated cable. Glover's started to manufacture cables covered with between one and three layers of rubber strip, waterproof tape and compounded cotton braid. In the late 1880s, Glover's began to make lead-sheathed cables for underground use. The company became a limited company and moved to Trafford Park in 1898, securing the exclusive rights for the supply of electricity to all the roads, streets and premises of Trafford Park. In June 1919, Vickers Ltd took over Glover's. Although Vickers held most of the shares, Glover's kept its name and management. In 1929 the Vickers group reorganised and sold its shares in Glover's to Sir Tom Callendar of Callendar Cable and Construction Co. Some shares later went to W. T. Henley's Telegraph Works Ltd. and British Insulated Cables. In 1945, Glover’s became part of British Insulated Callenders Cables Limited, following the merger of Callenders Cable and Construction Co and British Insulated Cables. During the 1950s, Glover’s developed high voltage submarine power cables, used to link centres of population with sources of generation. The parent company formed a subsidiary, BIC (Submarine) Cables Ltd, to manufacture and install the Glover’s cables. Glover's submarine cables linked England and France, and the north and south islands of New Zealand. Increasing competition from other cable manufacturing companies resulted in the south side of Glover’s Trafford Parks works integrating with the newly formed Wiring and General Cables Division of the British Insulated Cables Company (BICC). The Trafford Park factory closed in 1970, but the Glover’s brand continued as part of BICC.

Rolls-Royce Limited was established by Charles Rolls and Henry Royce in 1904. The company designed and built luxury cars and with the help of Henry Royce’s previous experience in building cranes, it soon gained widespread reputation for engineering excellence. During the First World War Rolls-Royce added building aero engines to its skills. This enabled them to later become involved in the development of jet engines. They worked engines for both the civilian and military market. However, a costly over-run in designing and building the RB211 civilian aircraft engine brought the company to financial ruin. Even though the RB211 proved a great success in 1971 the owners of the company entered voluntary liquidation. The government of the day bought the productive parts of the company which became known as Rolls-Royce (1971) Limited. Portions of the company were sold to British Aircraft Corporation and transferred the profitable car division to Rolls-Royce Motors Holdings Limited. In 1987 Rolls-Royce Ltd was privatised and subsequently became Rolls-Royce plc. The Rolls-Royce Motors brand was bought by BMW in 1998.
