I have a winchester 1894 30wcf octogon barrel, serial # 15XXX, the research I have done says it was built in 1895.. took it to a couple gun shops and this is what the one that acted like he knew something said... it was rebarelled(I dont think so) to a long barrel, it has 2 small holes in the side by the hammer, guess there was a different type of sight in it at 1 time. and the worst part is the 2 small brass looking braze spots in the metal peice that goes back into the butt stock. It does have double set triggers and what looks to be elk horn sights. they also seemed real interested in the leather sling that has double holes with brass hooks,buckles. that I guess is kinda rare. oh I did shoot my first deer with it 24ish years ago.and the action still works flawlessly!
