Here's a little bit better shot of it. It's hard to get the big picture with a digital camera that was obsolete 3 months before I bought it. If you looked down the barrel with a bright flashlight, you'd see the white hazy foggy stuff as far a the light will reach.
Best I can come up with as I don't have access to a bore scope unless I bring the barrel with me when I go for my next colonoscopy.....
