8/18/17 - This is an original Walther PPk finger extension magazine from WW2. The magazine has a very nice high polish blued frame with no rust or pitting. The left side of the frame has a Walther banner stamp only. The base is a thick lipped brown bakelite bottom, which makes this a semi-transitional magazine most likely made in the late 1930s or early 1940s. Guaranteed original and authentic, with a fully functional spring.
