I bought a Winchester 1873 Saddle Ring Carbine .44-40 last year for $900. Serial number 47513, which is a great number. Seemed like an awesome deal at the time but upon further inspection and talking to a few experts I figured out the stock of the rifle is off an 1866 rifle. But what the expert said is that he thinks by the way the stock looks and the screws, it looks like it was put on a long time ago. The stock has Indian style brass tacks and a silver star that is on it. Has original sights. Good condition, and good barrel, but would not advise firing it because it was made in 1879 when the barrels were of iron. Has never been refinished all original except the stock. So I was wondering how much is this rifle worth?
