Manufactured in 1900, the first year of production for Colt's first commercially available semi-automatic pistol. Features oval blade front sight and folding sight safety notch rear sight with the early pattern plunge-milled serrations (discontinued around serial numbers 1400 to 1500), two-line, two-block Browning patent date and Colt address on the left of the slide with circled Rampant Colt behind the slide serrations and the caliber designation on the right side, and the three-digit serial number "552" marked on the left side of the frame. Fitted with a pair of smooth oiled walnut grips (standard until approximately serial number 2449) and a correct nickel plated magazine marked "PAT'D SEPT.9.1884" on the base.

Very fine, retaining 80% plus original bright high-polish blue finish and 85% plus case colors on the rear sight and hammer, with some light edge wear, some minor thinning on the grip straps with mostly grey patina visible, and some scattered minor handling marks. The grips are fine with some scattered minor compression marks and scratches. Mechanically excellent.
