petsnazspetsnaz, those are some very cool finds, The silver button looks like some kind of military button, But I have very limited knowledge with buttons. The awl is what they call a "lighting awl" it is a trade item. The metal arrowhead was made by the Indian tribe of the region(Not a trade point). Square nails, I do not have any working knowledge on origin, my guess it was made by black smith's in the region, but that is only a guess.
