Guys,
Bill Ivey is a very close friend of mine so you have to take my comments in that context.
Bill and I have been collecting and studying North Carolina Longrifles for over 30 years. One topic of frequent conversation between us is where are the early North Carolina Longrifles made between 1760 and 1790? We have so few examples that we can study.
What we have come to realize over time is that the early North Carolina Longrifles will often look like Longrifles made in Pennsylvania, Maryland or the Shenandoah Valley of Virginia. When a gunsmith moved down the great wagon road to settle in Piedmont North Carolina he did not automatically change his style when he crossed the State Line. Therefore the earliest North Carolina Longrifles are going to look like Pennsylvania or Virginia rifles and unless the rifle is both signed by the maker and dated some where on the rifle, then it would be impossible to tell with certainty where this rifle was made. It is only when a Longrifle maker had lived in this area for a time and come to work and trade with other makers in his area did the new makers rifles start showing the regional architectural features that Bill so wonderfully demonstrates in his book on the nine North Carolina Longrifle Schools.
Bill is saying is that he thinks this Longrifle (and others in the book) might be from North Carolina. He is simply stating an educated opinion, not a fact.
As to the Makers initials being upside down on the Patchbox lid, there are several Longrifle Schools in North Carolina where the makers frequently signed their name on the lid. This is especially true in the Rowan School and Mecklenburg School. Quite often those makers put their names or initials on the box lid upside down so that the person who was holding the rifle could read it.
I hope that helps.
