1920 DWM S. Mg. 359 unit marking Mm?

1920 and 1921 dated military lugers were only made in the no suffix, a, and b suffix numbers;
not "n".
An Alphabet commercial in the "n" suffix would have been made later in the 1920's without any date, so any with a "1920"on the chamber would be a "1920 property" marking.
ref. Weimar Lugers by Still, p-13-14.

Are you sure it is an "n", how about a picture from the front of the frame?

Must have been sand blasted, glass won't move that much metal! JMHO.

There was an "n" series manufactured in 1920. See http://luger.gunboards.com/showthrea...light=n-suffix and many other posts.
