Its estimated that only the first 1,500 S&W No. 3 First Model revolvers have a small "oil hole" or vent hole in the bottom of the extractor housing making this example a rare variation. The rib has the one-line address/patent dates marking. The early production three digit serial number is found on the butt and on the back of the right grip panel. Matching assembly marks are stamped on the grip frame, cylinder, barrel, and barrel latch.

Fine, retaining 65% original blue finish with the balance a smooth brow-gray patina. 20% original case colors remain on the hammer and trigger guard. The grips are also fine with some minor handling marks and some high edge wear. Mechanically excellent.
