The frame looks like a Mauser frame (Mauser hump)
The toggle and receiver are DWM (former LP08 receiver)
The barrel is 1950s DDR (Ernst Thälmann Werke in Suhl)
The side plate is also 1950s DDR production
The grips are 1950s DDR production
The number 2 spare magazine is also 1950s DDR production.
If the loading tool has horizontal ribs at the finger lip, it is also a DDR made tool.
The first magazine (with the black bottom) looks like a post-war 1970s Mauser Parabellum magazine. It probably has the Mauser banner on the bottom of the spine.
The number 1 magazine is a pre-1945 magazine that was reused by the East-Germans (numbered to match the pistol).'
All in all a pretty consistent DDR VoPo rig. It only needs a holster
