I have an iron mounted rifle coming to me that has enough unusual features that made me get it. It's a fullstock flintlock. It's alleged to be a 46" barrel and 62" overall. There is forestock molding and an incised line at the bottom of the butt that stops at the trigger. It's a single trigger. The triggerguard it simple, with a downward pointing tip. There is no sideplate. If all that isn't weird enough, it has a sliding wooden patchbox that is pretty small, and just has a wood piece that slides in a dovetail, not a larger piece that covers the rectangular hole. And it has some simple scroll carvings (not high relief) on the butt behind the cheekpiece, and one scroll coming off the wrist towards the cheekpiece. There are vent pick holders underneath it. The iron buttplate is thin, and the plate is just moderately curved. I'll know more when I get it, and post good pictures instead of this.
I'm thinking SW Virginia, but I could be wrong. I'm afraid to guess a date yet, moderately early. What do the experts think?
