In 95% very sharp condition, we have a scarce and seldom seen Lightweight Duraluminum Frame 1940 early wartime production Walther PPK Pistol. This is a commercial grade finished pistol not one of the later wartime rough finished examples.
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. These very scarce dural PPK variants are highly sought after by collectors.
