This is a rare example of a Swiss prototype military test pistol. These were actually designed and tested after WWII when the Swiss were looking to replace all their aging Luger pistols with a more modern designed semi-automatic pistol. This design was actually based on the original Browning High Power pistol and is an almost straight copy. The only real visible difference between this pistol and a British High Power is the rear of the frame and slide which encloses the sides of the hammer, and then it has a slightly heavier slide (beefer sides) and a slightly longer and heavier rear frame rail. The internal components and barrel appear to be exactly like a High Power. The top of the slide is machined similar to the later Swiss P210 series of pistols with a drift adjustable front sight and fixed rear sight machined into the top rear section of the slide. The left side of the slide is marked with the Swiss Cross inside a shield with both the slide and frame numbered "11". The barrel is still in the white original factory finish and it is also numbered "11" on the underside of the barrel lug. It is fitted with a set of checkered walnut grips and comes with one unmarked HP type magazine. It is estimated that not more than 40-50 of these early test pistols were actually produced with several variations within this group noted, making individual pistols somewhat unique.
