Matching Luger question - Don't Shoot!

Hi all, I have a hypothetical question for you, but I may not be able to explain it very clearly. Please bear with me.


I have a 1937 military mauser from the "r" serial number series. The ejector is the only part not marked with the last two digits. It is unmarked.


If I were to find an ejector stamped with the last two digits of my serial number but from a different subscript (let's say the "c" serial number series), would my pistol be considered "all-matching?"


It doesn't seem like it should be, but as the Forum reminds me often enough, I'm a cherry and my instincts are seldom "right."


For the serious (advanced, superior, godlike or whatever they call themselves) collector: How do you verify that this substitution hasn't happened before, and does it even matter?


I apologize for any sarcasm, but sometimes the Forum is discouraging for a novice on a limited budget who can't compete with the big dogs.


Greetings and best regards from the U.S. Army. -Denny
