I agree with the over stamp. I had a gun once that had a 4 over stamped with a 2 and the gun was a 2. The scroll looks like Loy but I have never seen this engraving pattern. The dog would be a major clue but it in not sharp enough to tell. Loy dogs are rather distinctive. The S.S. are the initials of Sibley Scriver, the stocker. Runge senior was with Ithaca for a while. I have one gun his late son attributed to him.
Nice Crass!
