Many thanks for your kind input John, especially for translating the Sukashi design aspect. I had read on a very old post here (Circa 2007) that Yamakichibei Tsuba were highly faked. The Mei on our one is very faint & I struggle to get a good image of it. The Tokobetsu Kiecho Paper gives me some assurance, but I have read many opinions that seem distrustful of elderly Origami. I was hopeful for any opinions as to the veracity of this Tsuba's Mei.
