Miniature "Boys radio" crystal receiver
Red plastic cabinet. For medium wave reception. The radios look exactly like a "real" one, complete with tuning knob and a scale with a pointer. The receiver has a small earphone and two connecting wires with clamps for antenna and earth. The celluloid window in front of the dial does not fit anymore because it has shrunk.
The crystal was worn and had to be replaced by a new piece of galenite.

A look inside
A coil is wrapped around a rectangular piece of folded cardboard. A clamping bracket holds the prefixed crystal diode inside the coil. The tuning knob is used as a sliding contact on the windings of the coil.
