'Keemasabee': It appears your barrel muzzle was 'stepped' and notched to accept a 1903 Springfield 'banded' front-sight and cross-pin. This sight and the Krag barrel-band and swivel show up on ebay, often. (Search Krag and 1903 Springfield).

The butt plate will be a harder problem to solve, since it appears about 1 inch has been cut off your Stock Butt. This changes the dimensions and contour, so that an original plate will no longer fit. Your best bet might be to have a classic Pachmayr rubber butt-plate fitted.
