Yes, so am I. The m1863 Remington rifle- although a nicely built rifle, never saw actual use during the War. Hence, why so many are found today in excellent condition.
When the Italians began reproducing Civil War arms, they began first with the Zouave rifle. And folks bought them up- not realizing they did not see actual use. So then they began reproducing the m1841. While reenactors can use m1841s, the Zouave is practically worthless except for shooting and N-SSA matches. Reenactors can't use it, because many events ban 2-band rifles (in an effort to get rid of Zouaves from the reenacting field), and because they can't use it to portray anyone that used it during the war.
Meanwhile, 1841s are still being used, and hoarded over because they can be shot, reenacted with, displayed, etc. The m1863 is cheap because no one wants them. Can't even defarb them or change the setup to portray a Confederate produced 2 band rifle.
