Ferguson valve radio model 356U

Ferguson 356U radio. Walnut cabinet with a wide striped speaker cloth across the top, a cream tuning scale listing stations below and a knob at each end

The Ferguson 356U is a British four-valve tabletop radio dating from the early 1950s, generally around 1952-1954. It is a good example of the handsome wooden domestic radios that were popular in Britain before transistor sets became widespread.

Its cabinet was finished in walnut veneer, with a gently sloping front, large loudspeaker grille and illuminated tuning scale. It was designed as a substantial household radio rather than a portable set.
