Hey guys, I am new to this forum and don't know much about these pistols. Recently I inherited what I believe is an old walther PP 7.65mm. The box itself says Walther PP CAL. 7.65mm SERIAN-NR 700861. The side of the pistol says Carl Walther Waffenfabrik Ulm/Do Made in W Germany. I was unable to find any other numbers on the pistol. I was hoping someone who has a little more knowledge on them might be able to help me in finding out the history on this pistol and maybe how much value it may have.
