Martin, 
           I wonder if you've discovered this site which has many
Eddystone manuals etc.?
I suppose they might be the people to help with the information.
Good luck,
                 John.
P.S.
          Just remembered I have a bit more information with
regard to the sets made for the British Army, - when I can
dig it out!
