Sorry, I kind of lied. All of my prior S&Ws came to me as projects, and we got to talking about those, and after showing him the work I had done on mine he asked me to take a look at his. I am actually just going to be cleaning it up for him and giving it a general servicing but I was trying to keep it concise so I just said it was given to me so I could get to the point. In retrospect that wouldn't have added much length to the post... Unfortunately that does probably mean I won't get to shoot it.

Thanks for the tip about the sight. Based on that, I think it is probably pre-1926.
