An example of an altered model 1898 rifle leaf and eye-piece. These parts were altered at Springfield and became a variant of the model 1902 sight. (Note center notch and ground outside notches are slightly offset to right).

Mallory reports 110,000 model 1898 rifle sights were converted to 1902 pattern in 1903-04.
(The conversion would only have re-used the leaf and eye-piece assemblies. The bases had to be new, since, model 1902 sight-bases were taller and had a different spring arrangement).

Note - U.S. Krag rifles showed a significant bullet deviation to the Left upon leaving the muzzle, out to 1,100 yards, at which point, the actual bullet drift (to the right) brought the projectile back to and across the center-line. Beyond 1,100 yards the projectile continued to the right.

This bullet deviation was the reason rifle sight notches were offset to the right of the eyepiece index marks. (It was not for normal bullet rotational drift).

Carbines did not show this same deviation, so carbine sights had their notches centered and symmetrical.
