Magdeberg is the city...
interestingly, I have the
Schutzpolizei (Schupo or uniformed security police) Luger S.Mg.206 which is a reworked Erfurt from 1917...
The Landespolizei is the state level police.
If it is assembled properly, it should be easy to lift up the toggles and draw the breech block back from the chamber. It's possible that they have the little hook improperly engaged back where the recoil spring lever sits.
The lock lever above the trigger guard on the left should be easy to rotate down when you pull the receiver back slightly.
Do take care to ensure that this is not loaded before you handle it. If unsure, work outside and always keep the muzzle pointed in a safe direction.
