In 97% very sharp condition, we have a very scarce and seldom seen Lightweight Duraluminum Frame 1935 production Walther PPK Pistol. These Dural frame pistols were some of the first firearms produced with an aluminum alloy frame and they are by no means common. The use of this lightweight alloy metal was considered very exotic and innovative at the time. The Duraluminum alloy metal was developed by the Dürener Company back in 1909. It was used by Walther pre-war as a way to produce a lighter pistol and it does weigh around 1/4 of a pound lighter than the regular steel frame PPK. The one issue with these guns is that the anodizing that was used was not perfected at the time and it does show pronounced discoloration after 80 years. This pistol is all matching and has a mint bore. Later during WW2 another run of Dural framed pistols was done however they are not nearly as well finished or elegant as the pre war examples and the material was used due to steel shortages. These very scarce PPK variants are highly sought after by collectors, especially these very early examples.
