Make sure when you dis-assemble the locks from the frame, one of the first steps in a detail strip for any Smith gun, you have the locks cocked- different from a detail strip on a boxlock double gun. If the Smith you are buying is a post-1913, whether a R frame or a FW, the lock inletting at the head and radiused areas for the locks will be somewhat different from the pre-1913 Smiths- regardless of grade.
Also, if you find it necessary to pin the cracked areas at the head and tang(s) remember to countersink the pins at an angle to the run of the grain in that area.-- In woodworking, the term of "quarter sawn" better describes what I am trying to detail here for you. Would you maybe consider some before and after photos, so we can all benefit from your pending project??
