Even though this is now off topic I'd like to jump in here...
I too am sick of everything that's dug being called a "civil war" relic. Some of those CW item made it to the west and thus became "Indian War" relics with NO chance of proving they were CW military items. I've dug tons of military related "Indian War" relics that, to any unknown amount, may have at one time seen CW duty, but now were lost and found in Montana - thus an "Indian War" relic. My point? Not every three ring bullet ever fired is a CW relic... most were probably fired at game. CW "era" items lost all over the United States cannot necessarily be attributed to the CW itself. Not every buckle was lost in battle. Not every lead bullet was fired during a battle. Not every eagle button was lost in a soldier's camp. Some of that stuff might have been lost there 50 years after the battle.
Of course the chances increase dramatically if FROM a known camp or area... like where this item was found.
Back on topic...
I think the original item posted is a bell clanger, but do not KNOW it is. It's a good whatsit!
