The slide ruler is not Km stamped so it is not KM IMO. Besides, I have never seen this kind of markings on the box and I don't like it. It looks like the letters are individually stamped, some are not straight.

I haven't seen a Kriegsmarine property stamp like that before, either, and I am also suspicious of it.
