DWM 1920 "n" suffix research (Polizei)

[DonVoigt]

Let's resurrect another old thread with a new pistol in the "n" suffix series # 3218n;
but not with a 1920 date, but 1921 AND a 1920 property stamp.

This curious series and this seemingly out of sequence number continue to be an enigma.
I'm not sure this one will help elucidate and will perhaps only add to the confusion.

I "wanted" it as it was highly unusual to me to see a 1921 date with 1920 PS; only later I noticed it is an "n" suffix.

Obviously a police pistol, still with sear safety, had a mag safety which was removed and the slot welded and refinished. Pistol is matching except grips, and has #1/3218 magazine with */k inspection.
