Iguanicus-Rex's Documents Part 2 - NM-26 646-A, Box A778 1

Bonus Post. These documents were given to me several months ago by patron Iguanicus-Rex, who took them during his first visit to the National Archives. I've just now gotten around to examining them, I've done my best to sort and present what complete documents I could in view of what I was given. Because these documents are not mine I don't feel right making money off them, so this post will be free to the public.
