Blade front and windage adjustable rear sights, with the winged bullet logo next to "WEBLEY & SCOTT LTD/PISTOL SELF-LOADING .455 MARK I N/1916" on the slide, "'17" on top of the slide and chamber and on the right side of the frame, "crown" proofs, "broad arrow" stamps, and matching serial number on the underside of the frame and left side of the grip safety. With unmarked checkered hard rubber grips, lanyard loop on the butt, and full blue magazine.

Very good with 70% of the dark British arsenal refurbished black/blue finish remaining, areas of edge wear, shallow pitting visible under the finish, clear markings and proofs, and handling marks overall. The grips are also fine with well-defined checkering and some dings. Mechanically excellent.
