OK given that, let me ask you, did you need the President to issue it? or did the Navy?
Mine was Army (I don't suspect it makes a difference) but I don't remember the prez getting involved. Now, a lot of military docs contain the "signature" of the prez, such as, to the best of my recollection, my commissioning certificate, which of course the prez never saw, nor did the Secretary of the Army, and I believe his "signature" appeared there as well. Was the document you are referring to something that Carter actually had contact with, or was his name involved only as a formality?
