Many were sold off as surplus to be sold very cheaply, much as Mausers, Springfields, etc. were....the diff. is that at the end of the war they were rapidly becoming obsolete. They were frequently bought as a very inexpensive all purpose gun, going duty as a shotgun, varmint gun, barn gun etc. and were very hard used. Many scrapped, etc. There were alot of them out there, but were considered of little worth and as all tools, once worn out, discarded. Luckily my granfather found a nice example of an 1863 springfield in the local hardware store for about ten bucks, and I own it now.
