… I have almost every single book in the Practical Scrap Metal Arms series, by Professor Parabellum… Almost all of them. You see, there is one left, which I have yet to acquire; the file named "Full Auto Assault Shotgun". Actually, I have two dilemmas. The first being that I cannot find this book on the internet, and the second being I don't know where Professor Parabellum first posts his files. It's like they just appear out of nowhere. I'm willing to share my collection if anyone likes, but please, from one die-hard gun nut to the others, show me where I can find these ultra-rare jewels!
