Most likely, your pictures are too large, you can post pictures.
It seems from your document that what you have is a 1920 (the date) made weimar pistol, however the 'r' would be late 1920's - so I am wondering if it is a an 'n' ?? they made some 'n's during that period. Most were no serial (ns), 'a' and 'b' and for some odd reason some 'n's.

If an 'r', then it is a either a WW1 that the date was scrubbed or a later one that received a very late gov't 1920 marking (see the FAQ for more info on this).
