Thanks everyone for your help. That is great news. Does this sight go on a 1899 carbine stock. It does not seem to fit on my 1898 carbine stock. It also seems to be kind of awkward to use. I think the 1901 style sight is more user friendly.  I do not usually ask about value. But if I cannot use this sight what would be a fair asking price for it?
