This is one of approximately 361 Type III (late pattern) Model 1910 pistols reportedly manufactured by Webley & Scott in the 66300-66600 range. This variation is most readily identified by the lack of a grip safety and a combination thumb safety/slide release/takedown lever on the left side. It has a fixed blade front sight, drift adjustable notch rear sight, the winged bullet trademark and the three-line address and caliber marking on the left side of the slide followed by the "SAFE" marking, matching numbers on the frame, barrel and slide, Birmingham proofs, checkered grips, and a lanyard loop on the butt offset to the left side.
