Gentlemen, thank you for your feedback and the elaborate translation
I agree, an attribution to such a high ranking owner can only be ..ehhmm, well,.. optimistic, decorative or as Brian put it patriottic.
To complete your view of the pieces I made some photographs of the hamons, a little bit of the hada can be seen. But I must admit this is difficult to capture on such small pieces without a proper macro lense. I made a collage of some different blade sections and angles, please don't laugh at my Photostudio 2000 skills
Best regards,
Eric.
Forgot to mention; on the first pictures I posted the metal seems to have no colour at all, but that is because of the flash I had to use to capture the inscriptions. In real life the handles are a nice dark brown.
