Hi mike,
the holes in your wings , containing the cables ,would have been covered by a hinged flap which
would have been screwed/bolted through the small holes at the rear of the cable hole. At the top
edge of the flap , which if i remember right was usually rounded over like a tombstone , you would
have two " twist ,n, lock" fasteners to secure the flap down to the wing. The cables when not
being used, would be tucked away under the fastened down flap. The flap was of pressed metal with
a raised portion in the middle that the cables were run through when connected to the tuaam box.
The flap could then be fastened down without trapping the cables. The aerial leads should come out of the bottom of the wing box , be fastened to the inner wing then make their way along the
chassis, emerging through the floor in the back of the rear body, either as loose leads with
connectors on or as in the case of my lightweight , the leads were fitted to secure aerial fittings on the top edge of the bulkhead behind the seats. The leads do not come out anywhere
else on the wings. You are definitely missing the flaps on the wings. It may be worth joining the
"ex-military land rover association" or have a look at their website. They also have radio gear for sale at times.
Hope this helps
steve.
