Some Coleman lamp finials, most seen in brass, but nickel plated finials show up occasionally and consist of the a lower threaded section with nut to attach finial to a lamp shade and hollow center to pass a usually 12" lamp hanging rod through. The single far left item is not a finial but a lantern ventilator nut with threaded extension for attaching a lamp hanging rod, probably for use for hanging the first 242 Junior lanterns in a home, not common though.
