Introduced in 1913, the Mark I was designed with an eye for military sales, firing a semi-rimmed variant of the British 455 service cartridge. Fixed Patridge blade front and windage adjustable rear sights with Birmingham proofs on top of the barrel and slide and the Webley "winged bullet" logo on the left side of the slide ahead of "WEBLEY & SCOTT Ltd/PISTOL SELF-LOADING .455 MARK I/1913". The top of the slide and barrel shows small "'13" stamps, and the top of the slide is marked with a "broad arrow in D", traditionally associated with South African issued weapons. Fitted with a matching numbered grip safety, serrated ring hammer, lanyard swivel and a pair of ribbed grips.

Very good, with traces of the original blue finish, showing areas of brown patina, bright edge wear, and mild spotting and handling marks. The grips are fine, with some dings and scuffs. Mechanically excellent.
