Yes, that had pictures accompanying. I just couldn't imagine why there was a nice new firing pin with the rifle and a worn one in it, I was only about 19 then. It took some years to find out why. There's a picture in Pyle's book about the gas trap showing a gas trap that was found in the rafters of a barracks in Hawaii after the attack. All these years later it was fired and the round firing pin broke, detonating it.
