The document states that it is "Army Separation Qualification Record" form no. 100 dated 15 July 1944
Obviously this was a DA form (Dept of the Army)and not a DD form (Dept of Defense) such as the DD-214.
How you would obtain this document I do not know. I have been researching my father for many years and one of the places I wrote was to "Current Occupant" of the house that the family had owned in Stroudsburg, PA. At the time, several years ago, they stated that they had bought the house from a third party and knew nothing of my family. Several years later (2002) they found a box in the attic containing the form 100 and everything else you see on that page, the Individual Pay Records with promotion dates, the Certificates of Completion of schools and a Letter of Appreciation with first endorsement.
So, take a look at the page. This was the first I had heard of the form. If the link does not work again drop me a line and I WILL eventually make it work!
