....Well,... been studying on this a while,...... I like her,.. now .. for what it's worth, some observations of mine,... great different patchbox,... mostly seen in area where folks don't know if they are in TN or NC,... I have only seen two other double boxes and they used traditional catches,... don't know about the barrel tang,... trigger guard is from same mountain area,.. triggers seem to have a mountain area of South Carolina look,... Have seen a very few using a back-action lock made in the mountains,.. where was this gun found,...?? ... might have been made by a gunsmith who moved West from these mountains,.. anyway,... most interesting rifle I have seen lately, and hope to hold and examine one day,... thanx for posting,...!!! .... regards,...
