Its a cleaned up russian dipped gun (no biggie as long as you didn't pay too much) that's why the grips don't match, The Rusky's didn't take the time to keep the correct original grips with the gun, and the sear is not a horseshoe type its a std. sear and the sear waffenamt is most likely acid electro etched and under high power vis shows as little dots sometimes mimicking electro penciled. the blue dip was not completely removed from the locking block pin end and the trigger spring is still dipped blue too, The gold hue residue on the frame is another indicator of Rusky dipped ones as frames this early had nice blueing, the left grip may have been on an ac 41 with a horsehoe sear as its milled out for one, all else appears OK , should be an semi accurate shooter as the bore is not great, if you use rounds like winchester white box 115gr or similar light load as the ac 41's still had tight matching tolerances and are very accurate.
Hope this helps
