I don't know about the above marking but I just have bought and sold a Leica ll Kriegsmarine, with extremely autentical markings that was false.
I have a number of older good german cameras and i was cheated on this one.
I sent it away to an auctioncompany that sold it as a russian fake and i actullay got my money back.
