Fred - Yes, this is a truly fine Miller rifle, perhaps the best known. It is original flint. I looked carefully at this rifle when my good buddy, Jack, had it on consignment here in Denver. However, I passed on it since it seemed a bit repetitive as I had just sold a fine S. Miller (also original flint) incised carved rifle this past May which I had owned for over 30 years. The two special things, in my opinion, about this rifle (besides being quite fancy) are of course the rare take-down feature and that the design of the carving is very reminiscent of a earlier style "Golden Age" carving which I have never seen on a Miller rifle and which I believe, but could be mistaken, very uncommon for rifles of this period in the area where this rifle was made.
Thanks for all you do for this great blog.
