Denny,
Albert Ball's correspondence is often seen in some entire letters throughout the several books about him starting with the 1919 biography. All the letters from Albert to his father and to his fiancee are in the Nottingham archives. I have them all on microfiche. But permission to use them still lies with the family. I had to write a letter explaining my purposes before I coud get any copies.
They are very revealing -- very much the thoughts of a typical teenager who comes of age during a crisis such as the First World War was.
Did you want to know something in particular?
Cheers,
Scarlett
