Manufactured from 1860 to 1868. This is one of the approximately 4,400 2nd Issue revolvers that were marked "2D. QUALITY" due to a slight casting flaw during manufacture. This rare revolver is marked "2D. QUALITY" on both sides of the barrel, a seldom seen stamping. Matching "Y22" assembly marks are on the grip frame, barrel and cylinder.

Fine with 80% original silver plating, 40% original blue on the barrel, gray and brown patina on barrel and cylinder, some minor pitting, and aged patina on the silver and exposed brass. The grips are very good and have light natural aged coloration and minor wear. Mechanically fine. Provenance: Dr. Gerald Klaz collection.
