I have a pre-1900 Winchester 1887 12 guage that had its barrel swedged (spelling?). From what I understand a gunsmith would heat up the end of barrel and constrict the end from say an improved cylinder to a full choke. Of course this is way before threaded choke tubes. My question is how much does this effect the value of the shotgun if at all. Thinking about selling it.
Based on the guns serial number, it was manufactured in 1892-1893.
