This letter is also very strange. Normally one just goes into the Hospital and applies to the eligibility office. Their files of course are confidential. Almost as if he was trying to leave a paper trail.
Reading too much into it. The letter is 65 years old. Administrative procedures change. Before the omnipresence of computers, formal explanatory letters were frequently used to facilitate any activity, especially within the military. The military loved bureaucracy, at least it ran as if it did.

If you wanted something done, you did it in triplicate.
