The item with the hole in it I dug yesterday at a mid 1800's site that is a homestead today. It does not stick to a magnet so assumeing brass. The long item I posted last week but still no ID on it either.
The bottom item is a locking pin. Used on trailers to lock drop down side and back flaps.
Edit:
Looking again at the size against the coin it's probably too small for what i said. I know i used to play with one of these as a kid, thinking it made a great knuckle duster, and i know it was always in the draw of my mothers old cast iron Singer sewing machine.Maybe still a locking pin, as those old singers folded away upside down when not in use?
