Introduced in 1910, the Model 3 draws heavily from the design of the Walther Model 2, though with a reconfigured ejection port. Blade front and slide groove rear sights, with "crown/N" proofs on the slide and barrel, the Walther banner on the left side of the slide beneath the one-line caliber and patent markings, deeply cut slide serrations, external extractor, an extended barrel, checkered "CW" monogram grips and a nickel magazine. This particular Model 3 is photographed, described, and identified by serial number on page 30 of "Walther Volume III 1908-1980" by James Rankin, where the extended barrel and presence of the Walther banner marking are called out as being atypical for the model.
