Hi Marv, your post kind of excited me for a brief moment until I read the gunsmith you were looking for. If you haven't read the post just down a ways on this same page titled Lock by N.W. Patch, take a look. It is really something just how many gunsmiths had these same initials to their name's! There are several JD initial signed rifles shown in the red patchbox book by Chandler. Some used fancy * markings between the letters. Good luck in your quest to find pictures. Joel
