Gercolctor:  Your Model 1898 Krag was probably built in February 1903.  The stock stamp behind the trigger-guard is a stylized "P" in a circle.  This indicates the stock passed inspection.  If there is not a stock Cartouche (in a rounded square with inspector initials and date)  on the left side in front of the stock-wrist, your stock is probably a field replacement.  Your stock appears to be one of the Italian Walnut stocks that were purchased around 1900-01.  Your Krag has the 1901 sight.  The metal finish looks a bit rough on your Krag.  Your stock appears to have some small cracks.  I'd guess the value of your rifle at $550 to $700.  IMHO.  The 3 piece cleaning rod and oiler are worth about $55.  Its hard to assess condition and appeal based strictly on pictures.
