Swivel breech rifles are generally legendary in a camp or at an event. These heavy muzzleloaders are mechanically complex, but give marksmen double the firepower of a regular muzzleloader with the simple twist of the barrels.

Today we're looking at an original swivel breech flintlock muzzleloader from the 17th/18th century. J. Ernst Fielder was active in Ulm around 1760 per "Der Neue Stockel."

This combination gun has an octagonal barrel with seven-groove rifling and blade and notch sights and a part octagon, part round barrel with a smoothbore and silver spider blade front sight. Both barrels are signed "J. ERNST FIELDER IN ULM" in silver inlay with some accents
