The gun is obviously a very late flint, if indeed it ever was a flint. More than a few guns were built with converted locks that were never flintlocks in their working life. I just feel that reconverting is disenjenuious. Conversions were done in the past to increase the guns value, because flintlocks often bring a higher price at auction. That isn't always the case today. Many collectors prefer to represent the gun as it was for the majority of its working life. And, often consider a reconversion suspect in other areas because of this "restoration".
