Vintage Brass Spherical Finials Newel Post Caps Bed Knobs

vintage spherical brass finials for bed post knobs, staircase newel post caps, or would be lovely on a wooden gate post I have given these a cleaning and a very light polish, as I love to preserve natural patina when I can, but they could easily be polished to a mirror shine if that's what you prefer the screws are quite oxidized, but undamaged in good vintage condition ~ as stated there is a natural patina on these, and oxidation of the screws measurements: approx 3" diameter approx 9.75" circumference approx 1.5" length of screw
