Thanks for the chart, and the background information.
Mine's an AF, 1980.
My thought on this- wow, this pistol is 39 yrs old, and takes a pretty thorough inspection to determine it's NOT brand new. I have a white spot on the frame inside the trigger guard, where the knob on the back of the trigger makes contact with the frame. I have a couple speckles on the left of the slide, in the bevel near the muzzle. Nothing alarming, it's just that you can see them if the light is right, and the right side is completely clean. I have a couple hairline scratches on the right side of the slide. I mean exactly that- hairlines. You really have to catch the light just right to see that, generally they look clean unless you see that. There's a little spot of wear on the front of the left side of the slide.
There's a couple areas of the grips where the shine is worn some, and maybe a small scratch, like from a fingernail, on the right grip.
The trigger itself has the very slightest plum tint.
I mentioned this on another forum when I received mine from Classic (and no, I didn't pay for hand select): these are found by SERIOUS examination of the handgun, not by a casual glance. I have to look closely, and move the gun in different angles under a bright light, to catch the slight light variances of the "marks". Other than the small fingernail mark (if that big, as it would have to be a small fingernail), I can not feel anything.
To clarify, I've seen more marks on a "new" gun at a store, just from being handled and placed on the counter a few times.
