I have a 1933 commercial PPK, it has a serial number on the frame, but I cant find any serial number on the barrel or the slide, is this correct??
Thanks, Titan
At that point in production the slide was not numbered externally. Use some indirect light and look inside the slide, opposite the ejection port. They usually have the last three digits of the serial number electro-penciled there. The barrels were never serial numbered. The barrel should have a crown over N mark on the right side near the muzzle.
