David, unfortunately very little to nothing survived of the electrical system., Again, on Ebay I was lucky to aquire a complete original maintenance book which has wonderful information like the photos shown here. That old saying of never say never' as you just don't know where and when something might just come your way. I have been waiting very patiently for a turret to drop in my lap but I won't hold my breath for one of those. I do have a number of drawings for that part as well.
Colin.
