Part of the initial run of Walther's military P.38s, the Zero Series served to "fine tune" the Walther HP to Wehrmacht specifications and was an important stage in the pistol's development. These Zero Series pistols are very scarce compared to standard production P.38 pistols and have become extremely popular among collectors due to how they illustrate the important changes made during production of the model. This particular example is a third variant of that series. It is fitted with fixed sights, a round firing pin, a serrated takedown lever, and an exposed extractor. The slide is marked with the Walther banner and "P.38" on the left, with "eagle/359" proofs on various components, matching full serial number marked on the slide, frame, and barrel, matching partial numbers on the locking block and inside the grips (the left panel has "878", likely a factory error), and unnumbered later production replacement magazine.
