Could anybody tell me anything about the well known fake KM dagger with the engrabed blade with eagle and swastika, battleship and Kiel monument? Do you know the date when these daggers were made, maker...?
Is there any posibility that any dagger with this kind of blade does exist before 1945?
Thank you very much in advance.
