I have discovered a possible meaning for Burgunon!!
The area in France, called the Alsace-Lorraine, has always been a place where German and French people lived (and fought). This area is also near Burgundy, famous for the wine and good life.

The german name for Burgundy is Burgund, the French name is Bourguignon. Could the name Burgunond (on the flintlock), be a mixture between the two languages, meaning Burgundy?
