We have discussed alot of CW era shells, and then some of questionable civil war usage shells, but unless actually "dug with providence" how can you tell if it is actually a civil war used projectile? The actual question which comes to my mind, is there a record of when each shell { or Gun}was withdrawn from use, here and then possibly abroad? I 'm assuming just for a example, that a 3" parrot was used post war, but how late? and were the remaining guns demilled, or sold to other countries. Confederate shell were obviously not produced after 1865, but how long were the others used? Are some of the dug "CW" relic shells available actually post war dug relics from some firing range possibly out west, making a relic w/o providence a CW "type" shell? Just Curious on some views on this subject as I'm not sure if any muzzle loaders were still in use by the span -am war
