Thank you for the information LugerDoc, but correct me if I am wrong the KM Mauser mags (from what I thought, and read) were matched by serial number, and property number. My 1940 Kreigsmarine N4425 592 has the magazine from N4422 109. I am thankful to have a N prefix magazine, but would love to pair up pistol with its original magazine. And vice versa if I found the owner of N4422 109 if it still exists

I would happily reunite the pair.
Thanks again
And I just notice in response to Ed's post the matching magazine post on this website.
