I have a c marked 1998 sight which has been modified to 1902 style, rounded off and "sargents" peep added. Did they do this to 98 carbine sights? The base seems to be faked, little less the 3/8" at hi point of arch, which looks to be too high! Is there any way to tell if the Leaf is correct, other then the c, which looks correct? The c on base also looks correct as to size and matches the eye piece c and both appear the same as Brophy pictures! I have never seen such small stamps made for the general public, tho I do not rule that out.
