Well I have one and am still not sure how much help I can be. They were marketed as a Dixie Lancaster rifle, .45 caliber and available in flint or percussion. Made in Italy but I never determined the actual maker. Mine was flint but I honestly never shot it much because the lock was a very poor sparker. Years later I put a percussion lock on it but I had so many other guns by that time that I just didn't shoot it much. Dixie recommended a .445 ball, but that was too tight in mine so I went with a .440. Rifling was very shallow, and no crown on the barrel. What shooting I did didn't give great groups, but ignition was so unreliable I probably never really dialed it in. I still have it, I should get it out and fool with it.
