Hi Kent,
The intention of the display is to show early rifles in America in addition to those with some Rev War provenance. So it was not just PA rifles. They had one of Ernie Cowan's Ferguson replicas there as well to display an early breech loader used in the war. Unfortunately, despite all the hype about strict historical accuracy Cowan and Keller included in their write up about the Ferguson included in Bailey's book on British military rifles, they screwed up the color and finish on their gun. I don't know why it is that so many guys insist, despite evidence to the contrary on every British gun at least, that every military gun made in the 18th and 19th centuries had stocks colored really dark and looking like they were dipped in linseed oil and left to dry dull with an "in the wood" oil finish. British military guns, including the Ferguson and I handled the original in Morristown, were finished with a slightly glossy linseed oil VARNISH and many, if not most, are not almost black in color now nor when they were made.
