Jim,
Kindig’s “Thoughts on the Kentucky Rifle...” has a section on the Gobrecht family guns. I have an unsigned and uncarved Gobrecht flintlock rifle with the features Kindig mentions, such as the unusual patch box finial, the long front section to the side plate, and the front and back trigger guard tang file notches. Although not a high art or finely crafted piece, I am very fond of it. It is good to know that you have one to be proud of, brought down in your family.
