From what little can be discerned from the photos, it looks like a pukka III or IIIa (Cameraquest lists it as a 1939 IIIa)- the viewfinder window is stepped below the top plate, rather than flush as on a Fed. Check that the rangefinder arm has a roller bearing, rather than a plain shoe. Who knows where the engraving came from, although it looks suspiciously fresh compared to the Leica logo and serial number. If you want it, value it as a straight IIIa with Summar(?) and tape over the engraving unless you’re into WWII re-enactments.
