Fender ID question

O looked inside the fender and see no actual signs of seam welding of any sort. It also appears that the fender inside does not appear dented and filled which makes that body line very strange and way to round compared to the line on the top fender in my pictures. At any rate, I guess I am lucky to have the other two fenders I picked up with the correct holes, but as you can see from the top photo, they too need some body work? Should I just use a tapping hammer and a shrinking hammer to try and get those dents out of that top fender?
