This revolver's serial number dates to 1853 and it was subsequently converted for centerfire ammunition in the mid-1870s. It features elaborate feathered scroll engraving with punch-dot backgrounds, an eagle mask by the wedge on the left, another mask motif on the hammer, floral accents, and a variety of border patterns. The ejector housing and cylinder display a slightly different style of factory engraving. The barrel has a brass cone front sight and the one-line New York City barrel address. The left side of the frame has the small "COLTS/PATENT" marking, and the loading gate is numbered "398." The ejector rod button is installed backwards, and some of the chambers are wider at the outer wall. The revolver is fitted with a smooth grip.
