3/26/20 - This is a very rare 1st variation (and 1st year of production) Walther PP finger extension magazine. The magazine has very early features including an open follower. The magazine has minimal wear and is in excellent overall condition. The black bakelite finger extension has a serial number stamped into the right side of the extension - a practiced followed by pistols given to the Reichsbank, or bank of Germany. No cracks or chips, and a strong fully functional spring.
