Vent Window Rivet on Upper Pivot

Happen to be working on all my windows and glass so can share some photos. These vent wing parts have been removed for cleaning/polishing.plating. One of these pivots was good but the other was rusted. So one of these buffed on my wire wheel and clear coated. Can you tell which one? If you look really, really close you can.100_2406.JPG100_2407.JPG
