Gentlemen, Im new to the KCA.  Back in 1995 my father passed and I was given an 1898 Krag that originally was my great grandfathers.  My grandfather put a Lyman peep sight and Bishop stock on it but left the barrel in its original 30 inch configuration. Sadly the original stock is long gone. My grandfather, father and I bagged our first deer with that gun. Killed like lightning. SN477245. Wanting an original military configuration, about 20 years ago I found one, SN 151711. Stock cartouche script JLA 1899.Snapped that lady up right away. Finally decided to do some research and in Brophys book i noticed the rear sights on both rifles were 1901 type with small aperture hole, "V" shaped sighting leaf notch and windage adjustment bar. The serial number blocks show the earlier numbered rifle to be manufactured between July 1898 and June 1899 while the late rifle was one of the last 500 or so produced -1904. My question- Is the sight on the earlier rifle as issued or was it a rearsenal? Was the 1901 sight issued in 1901? If so its odd to have a 1901 sight on a rifle approved for issue in 1899. Finish and patina match and are consistent and im not planning to change anything. Any information would be greatly appreciated.

Thanks so much for the information. I read on Bowers Firearms Springfield Armory US Krag-Jorgensen Serial Number Ranges that SN477762 was the highest number. Obviously , thats false!!!
