I forgot to tell you that it has an octagon barrel but I think your answer covered it.
I found some paper work that came with my gun and it shows a M1886 that has a 28"
barrel. My barrel measures 27 1/4" from barrel end to where it attaches to the magazine. Would this have any difference in the value's that you gave me?
My Winchester is a 40-65 MFG. between 1889-1890.
