Walther / Hammerli / RWS lines under Umarex context

CountryGermany/Switzerland heritage; current U.S.TypeHouse / importer / platform brandPlatformUmarex USA / Umarex GroupCatalog35 models

Walther, Hämmerli, and RWS airgun lines sit within the Umarex ecosystem but require product-family separation between target, replica, and sporting airguns.

In our words

These names carry real heritage, and buyers should know which lane a specific product is in. A Walther target pistol, a Hämmerli recreational gun, and an RWS/Diana-style springer should not be flattened into one generic Umarex line.

Real-world commentary

Walther and Hammerli carry target heritage, but current U.S. products vary widely. RWS can mean pellets, springers, or legacy Diana/RWS context.
