Manufactured between 1962 and 1970. Adjustable blade front and fixed notch rear sights, the MBAssociates model and caliber markings on the left side below the barrel, the patent on the reverse, nickel small parts and a pair of smooth grips. With an unnumbered factory box.

Excellent, with 95% of the original matte black finish showing a bit of wear and spotting overall. The grips are also excellent. The box is good with some mild spotting and tears. Mechanically excellent.
