I believe that the front sight is original, the white outlines on the rear sight is not. Could have been either a V notch or a U notch. Some disagreement on when that happened. Mine from 1916 has a U notch and a patridge front sight. If you take the sight off, it will also be serial numbered to the gun if original. Looks like the stocks have been modified, the "hump" is smaller than original. Overall a great find and one not seen often. I shoot mine all of the time, get a lot of looks as well, especially after I tell folks it is over 100 years old.
