Hi I really appreciate the replies. I was offered two C&J naval daggers. One with the etched makers mark and the other with the dual stamping. Although I could find no fault with the quality of the etched maker mark I decided to purchase only the one and passed on the other.......I believe that regardless of pre or post war it would be virtually impossible to sell it at some point for the price offerred. Has anyone seen a period Robert Klass plain blade Kriegsmarine dagger offered for sae? thanks and regards, Ryan
