Is it my eyes or the picture, but looks like the serial numbers have been polished out...
I don't think it's your eyes. The rifle in question is not an option for the op now, which is a good thing. He found a much nicer example. You should check out the other thread he started. Not a lot of Winchester experts commenting on this rifle, but there is a lot that stands out in those pics. Like I said, that rifle has been picked up a lot and examined at a gunshop somewhere. In person it is probably even more obvious that the finish has been re-done etc..
