The "1934/06" is just a designation indicating the year of manufacture/configuration. The 1934 Mauser Commercial fits this designation being a Mauser "banner" commercial with a 1906 style frame and grip safety. The Portuguese GNR could be considered a 1935/06. Keynyon's "Lugers at Random" is a book reference. Although outdated, it remains a primary reference.
The Swiss, Bulgarian, German Navy, Dutch, US Test, Portuguese and Brazilian Lugers are military examples with a grip safety. The remainder of the grip safety models are by and large Commercial models and can be found on Model 1900, 1906, 1908, 1914, 1920 and 1930s-era Commercial Lugers. Whether the "Russian" Lugers are military or commercial is still part of the controversy!
Early Model 1900 grip safeties extended only about half-way across the grip. According to data collected by Dwight Gruber, around serial number 10010 the grip safety was widened to the full width of the grip strap and remained that way througout the rest of Luger production. With the introduction of the Model 1929 Swiss, the grip safety was made into a "wrap-around" configuration that enclosed both sides of the grip strap and was significantly longer top to bottom than previous models. This type of wrap-arouind safety configuration was continued on the 1970s Mauser replicas.
