My artillery trailspike appears to be stamped CONN, which means it could have belonged to 1st or 2nd Connecticut Artillery? I'm not sure what cannon the 3rd used, or if there were any other Connecticut ligjt artillery battery's. I'm guessing there were fairly low numbers of Connecticut trailspikes, (as opposed to rifles, pistols etc in the thousands). My imagination has me wishing it was one of the ones in this photo from an earlier post showing 1st Conn light artillery with trailspikes attached.
