there are many things that determine the value of this rifle.the first item being that you have a Winchester mod 1876 third model that was made in 1883.second is the overall condition of the firearm.(is the finish worn away or does some still exist?).is the rifle complete and does it function? is the bore dark and pitted or bright with no pitting?is the stock complete,not broken and retain its original finish if any? as a guide this rifle could expect to fetch between 2,250-3,000 in above average finish down to 1,000-1,600 dollars in below average condition.
