Hi David S.,
I noticed the asteriks mark on your PPK under the serial #. For what it's worth....Your gun was probably a European police gun and that mark was to remove a police mark/proof. I was told that these marks had to be illegible in order to export the guns to the US. The 69 issue is intersting as well for obvious reasons. 1960's PPK's are amazingly accurate as you found out. Personally, I've never understood why gunwriters go on&on about the Seecamp as an acceptable self-defense gun, but a PPK in the same caliber or .9mm Kurz is unacceptable...go figure!
