I have received letters on 4 of my model #3s which were a joy to receive, as I experienced some surprises. As to my latest, a 1st model Schofield, being "U.S." marked, unless someone here corrects me, I don't see a point in it. Since acquiring it, I have seen 2 for sale listings where an S&W letter was included. Both letters were word for word the same. A little history informing the requester about sales to the 2 N.Y. retailers & how they were sold to the Army. Also, that of course, there is no info on which unit received it. Any possibility of a surprise here? Thanks!
