Radio Control Equipment for Models, 27Mhz Band

This is kit-built old-school 27MHz 6-channel gear, comprising a transmitter, receiver, three servos and a spare pair of crystals. 
I can't verify its present working condition as the receiver battery is missing, but the gear was in good working order when put back into its original box (and then forgotten about!) some years ago. 
The Tx was powered by two 4S NiCd batteries. Although these are still in place they are almost certainly non-functional now and would be better replaced by a rechargeable lithium battery pack. The Rx was powered by a single 4S NiCd battery (not included). 
The Tx circuit was modified by adding switches to select full-throw or half-throw actions of two of the servos.
Assembly and operating instructions for the Tx, Rx and servos are included.

Buyer to collect. Cash only please, as I can't accept electronic payment.
