Rooster posted this photo on a different thread the other day and something caught my eye by the cover dowel.
I recognized the marks right away because my sand cast gear cover for my 51 has similar marks, though in a slightly different location.
If I had never seen the photo Rooster posted I would've continued to assume these marks were from some one having the cover clamped in their bench vise for some type of repair and would have blended them out. Now I will not only leave them, but do whatever I can to preserve them. It's amazing what you can learn from one photo. So I was wondering how many others have seen similar marks on parts? I guess they were left by the clamps at the milling machine when the screw holes were counter sunk. I wouldn't have thought something like this would pass quality control, Guess I was wrong.
