I have a Russian capture P38 which has had the serial # at the base of the barrel ground away, very skilfully, very smoothly, and very flat. A new number was stamped very lightly in that space. The same number/font is also stamped very lightly on the left side of the slide, and more heavily and with different font on the right side of the frame.

Is it possible that their Lugers were marked similarly??? And a faint # corroded away???
