I believe those examples are after OCR has been applied.

I only have one pdf in my collection which is not OCR'ed. It is an old copy of small arms guide I found on my backup drives.

I have attached a screen shot of what I think is the original font.

I have run it through multiple online resources to identify fonts and have not found an exact one. The key points I noticed on the font were the shape and width of the lower case "e" and "a" the curvature of the bottom of the "9" and spacing after the "1".
