This turned up recently, and its pretty unique. As best as we can tell, its some sort of INAAP history booklet, perhaps handed out during tours or at some conference or another. It looks like it was written by someone at the plant, as it contains a great deal of information about INAAP; its history, its capacity, workforce, etc etc. While it is missing a few pages (2, 20-22), it is still a remarkable little document. Of note is the reference on page "8" to the fact that 1,000 German prisoners of war worked at the plant at one point. Hopefully someone finds this stuff interesting. Rather than hosting it as a pdf, it is set up as pictures that are viewable one at a time.
