I'm very surprised that Glen's deliberate mistake hasn't been spotted yet. It's on picture 3 on page one of this thread. I'm sure Glenn has just done this to wind us up, but I for one have spotted it. Old Eagle eye strikes again. lol.
Harry:
My greatest mentor explained to me that these things are not errors or mistakes, they are "features" and "options".
The onliest such feature in the picture I can see is the timing (or "clocking" for you British types) of the screw on the top of the tang. If that is what you are referring to, you are correct. It was left that way deliberately. As a screw that compresses wood, it will want to be tightened just a wee bit after the rifle has been shot a few times.
