This is an ultra rare and early Walther PP magazine with a red bakelite finger extension base. The red finger extension was only made for a short period of time as an experimental style finger extension by Walther. One of the hardest to find, and perfect for an early / pre WW2 production Walther PP. The finger extension is early thin-lip style with a "slab side" or no side indent. Strong spring. Left side of mag is marked PP 7,65 m/m underneath the Walther banner. The right side is marked with a W. See pictures for full details.
