This variation's name comes from actual Sauer factory records found in the Suhl Archive. An interim pistol produced during 1926 to early 1929 period. Found only in 7.65mm caliber. This was an advancement of the normal 1913 design, which included changes in: (1) safety lever's design that became a slide hold open device as well; (2) shape of the frame was altered in that the triggerguard became more streamlined and the rear of frame was shortened and serrations were added to the slide as well as cocking knob. These are found in 162000 to 169000 range in relatively small clusters. Two to four thousand are presumed to have been manufactured. A scarce Sauer pistol! To date, none have been seen in nickel.
