Blade front and frame notch rear sights, two-line address and patent marking on top of the barrel, caliber marking on the left, Colt "VP" proof and "3" stamps on the left side of the trigger guard, finely checkered trigger and hammer, and checkered back strap with a small flourish of scroll engraving (most likely factory, although we cannot document without letter) at the top, checkered medallion grips, and lanyard loop on the butt.
