I'm not a collector of Confederate arms, can't afford them. I'm curious though, I've never heard the term "confederate horn" used to refer to a sight on a rifle. That looks like any typical buckhorn style rear sight you'd see on a rifle from 1840 until yesterday. What is it about the sight that leads you to say it's Confederate?Well, that definitely looks like a Confederate 'horn' rear sight...
This is fascinating.
