The pocket pistol series includes the Model 1910, Model 1914, and Model 1934. They are very similar to each other with differences of caliber and small features such as the shape of the grips. There are also other rare variants such as the Model 1912-14, which were experimental and did not go into production. These pistols are fairly common yet uniquely well made, well finished compact pistols. The Model 1934 was a standard sidearm of the Nazi Kriegsmarine (Navy) during World War II.
