New to the forum. I have a 19-4 4" blued with TT & TH that I bought new in the mid-70's. SN 35K60xx. I don't remember ever having shot it. However, the pad on the cleaning rod that came with it does have oil on it so I cleaned it for some reason years ago. There isn't a mark on the bluing or square butt grips. It's time for me to let it go and I could use some help setting an asking price. I have the box and everything that came with it new.
