Hi Colin, a standard 8cwt would have a table on one side, not full length, for the radio to sit on. That, and the 2 seats,and the rest of the equipment. At this precise moment I'm not sure where the chore horse battery goes. Then in the cab theres the two-pin plug, the pto, earthing wires, all good fun. Initially it would be an 11 set radio, but that would be replaced by the 19 set shortly after.
I dare say they were used in the Normandy campaign, as there was no such thing as a rule book for anything, despite what people say, but originally, for a truck used in, say Africa or Italy, an 8cwt would still be used. Bearing in mind that the C8A HUW appeared in 1942, only to be superceded by the 15cwt wireless truck, standard body, then the solid body soon after. For a war on, with short supplies, odd choices were made.
If you ever find plans for early Morris or Humber 8cwt radio trucks, the body was pretty generic, if not, I can attempt to scan some shots for you. Attempt is a strong word.
