As the experts have opined, assuming the bore is good and there is nothing wrong they cannot see, that is what you are looking for, "all original in nice shooter/hunter condition."
It seems the owner was a little careless, as there is no reason to use a sling that continually scratches the stock. But, it isn't beat to hell either. The trick now is not to pay too much. But if it is what you want, paying a little extra will be lost in the noise, especially if it will shoot itty bitty groups.
Not only that, but Godogs57 is always your "safety valve" : )
