Summary
A crystal radio kit comprising a green cardboard box with a removable lid. The front cover has a colour illustration of a man holding up the crystal radio kit to a boy wearing an ear-phone wired up to the radio. Inside the box is an instructions booklet printed on cream coloured paper and the radio itself. The radio is a rectangular piece of grey plastic with a large circle cut out of the top. Fitted inside this circle is a piece of green cardboard on which is printed a circuit board diagram in white. Protruding from the printed diagram are nine metal coils, some of which have different coloured electrical wires between them. Each coil is numbered from 1-9. The pink plastic ear-phone is wired up to coils 4 and 9. In the centre is a black and red antenna coil. On the left hand side of the radio kit is a grey plastic tuning dial which moves between 0 and 10. Total number of items is 4.
