In the early 1950s, Manurhin acquired a license to manufacture Walther PP and PPK pistols. Identical with the original Walther products, these could be distinguished only by MANUFACTURE DE MACHINES DU HAUT-RHIN on the left front of the slide and LIC. EXCL. WALTHER, with model and calibre, on the left rear. The grips had MANURHIN molded into the upper part and LIC. EXCL. WALTHER in the lower portion.
