It bears the 'Gecophone' logo on the front of the set
and the "Entirely British Manufacture" BBC
transfer on the
back of the set.
Connection points for the aerial, earth, optional coil,
glass enclosed galena detector and headphones
are provided, and the controls comprise a tuning knob
and a lever to adjust the cat's whisker. |
