From gracesguide.co.uk:

1949: A separate private company for marketing tape recorders was established, the British Ferrograph Recorder Co Ltd, owned by the same shareholders as Wright and Weaire.

1955: Wright and Weaire was converted into a public company and acquired the share capital of Ferrograph.

1958: The name of Wright and Weaire was changed to the Ferrograph Company; manufacturing activities transferred to a new subsidiary Wright and Weaire Ltd.

1959: Ferrograph was absorbed by the Wilmot Breeden Group and it was decided to add to their hi-fi range with higher powered amplifiers, radio tuners and monitor loudspeakers.

1977: Falling sales resulted in heavy financial losses for the company. In order to safeguard jobs the National Enterprise Board arranged a marriage between Ferrograph and North East Audio Ltd (NEAL). Wilmot Breeden sold the Ferrograph company for £500k.
