This is a English made .577 caliber muzzle-loader. Back in the 1970s Parker Hale of England made the best copy of the 1861 ENFIELD pattern carbine. They called it a Musketoon in some of their ads. Other places call it a cavalry carbine or artillery carbine. This one is in excellent condition and I only fired it at a few matches over the years. The Enfield Rifles and Carbines were used by both sides during the US Civil War. I have a couple tins, ( maybe more) of Musket Caps. I no longer have the bayonet. I also have some cast and lubed Minnie Bullets. Text or call for better photos
