A better view. The crown N proofs are slide, frame and barrel. The mags are Walther marked, but no serial number markings. Bore is mirror, small hairline cracks in grip at screw bushing and top center rear of grip.
Holster maker is AKRAM.
The other two are totally different in marking from yours. One Arbeitsgau number is on the front grip strap, the other marked just RAD on the frame. One .22, the other 7.65mm. No apparent serial range. One in the 214xxxK range, the other in the 238xxxK.
