I didn't see this until this morning (yesterday I was in Ilion, imagine that). John where abouts are you located in NH? There are several knowledgable members in NH and (John Dunkle
). A few of us shoot at Major Waldon's on a regular basis and it would be an easy place to meet. There are also a couple of gunsmiths some of use who are familiar with doubleguns. PM me and I'll fill you in.
