Found this on a very old property property was purchased in 1790 and their son was a soldier in the war of 1812 they bred championship trotting horses and had a early hotel that burnt down in 1916 I have no idea what this is any help appreciated
Noah_D's guess (he said "can't decide" and "I'm thinking") is correct... your find is a brass "thimble" (a.k.a. ramrod guide) from a Colonial Era flintlock musket. Its size tells us it is from a musket rather than a flintlock pistol.
One of the key ID-clues is the presence of a notched (or holed) flat flange running along the brass tube's upper side. That is how it was attached to the gun's wooden stock. See the images below.
