From PRC Data series by Dennis Starks:

"UK/PRC-316; Manpack portable HF/AM/CW transceiver. Built in the United Kingdom originally as the A16, the PRC-316 is similar in concept and purpose to the U.S. PRC-64. Though extremely small and lightweight, it must be set up for operation & cannot be operated while in motion. Features: Very simple operation, 45 xtal control channels. Built in antenna adjustments allow the use of 1/2 wave dipole antenna.

Code burst operation at 300wpm using GRA-71 code burst generator. Ops 2-7mc with a peak RF output rated at 4 watts. Power is derived from a 12vdc battery mounted under the set, or any external 12vdc source. Size 7.9 x 4.4 x 3.5in. Weighs just under 5 lbs less battery. Known accessories include a 1/2 dipole antenna adjustable to frequency. Optional single unit microphone/receiver or conventional double receiver/boom microphone.

Adaptor Unit AN/GRA71-PRC316

This box has a storage compartment that holds the 4 GRA71 components.
This box has 2 pairs of plugs (and sockets on the bottom) that appear to be there to connect to a couple of batteries?
On each side there are 4-pin sockets. One marked PRC-316 and the other marked Headgear.  They are exactly the same socket, that is to say the dog bone cable will fit either socket.

5820-99-110-6651 Dog Bone Cable

There is a 4-pin socket labled "PRC-316" and a short dog bone cable that connects the adapter box to the PRC-316.
Both 4-pin connectors on this cable are the same and are: Thorn 05-0271-8-4P, TBL 05-1001-8-4-2

5820-99-110-6652 Interface Cable

The "Keyer" 6-pin socket on the Adapter Unit connects to the TBL 05-0020-10-6P connector on this cable.
The other end of the cable with the 7-pin connector connects to the Keyer.
