Hello Westwind! The magazine is for a Luger! In fact, it is for a Luger made in 1937 and, in addition, the Luger is known as a 1st SubVariation. This means it has a strawed finish on some of the small parts (take down lever, magazine release button, trigger, safety lever and ejector). The Luger was completed about February of 1937. I hope this helps!
