Marconiphone:      (see also 'Thorn', 'BRC')

NOTE: Ferguson, Ultra, Marconiphone and HMV were, for many post-war years,  brands of  BRC (Thorn) and some chassis are common, especially radiograms and record players. If you cannot be sure of your model, look for a label with a number, often attached to the inside of the cabinet wall or bonded to the rear of the dial plate. The number will refer to the chassis production schedule. Use this to locate your receiver under 'Thorn' or 'BRC'.
