four channels.

 Working condition.

This is a  transmitter-receiver used in airplanes like Lancaster etc. It is a four channel unit. For the receiver, as well as the transmitter, four crystals are used.

It is remote controlled by a switch box. On the picture a replica controll box is used. But the whole unit is working. Supply voltage is 12 volts, which indicates it is an earlier one.
