Re: 1873 winchester
Nice!!! I have soft spot for the 1873's. I have the same round barrel rifle as yours that was produced in 1881. Unfortunately, there is little rifling left in mine....you are very lucky to have a shooter. I also have a matching 1881 Colt Lightning six shooter in 44-40 produced in the same year, complete with notches on the original grips. The pair makes for a great display.
