Thank you for your corrections and pictures! I have just flipped the blade correctly.
Looking at the blade I can see the "Y" stamped part as a rocky wall, the silver inlay as roof tiles and the "water" pattern as clouds behind the wall. I remember seeing that pattern paired with clouds on a woman's kimono in a painting and found out the pattern is called Tate-waku (rising steam).
So this style of sword fittings was created by low-ranking samurai in the Sendai domain as a means to make a living, but because these would be sent to be sold in the Ogaki domain they are known as Ogaki Koshirae/kozuka? Sorry for rephrasing, I just want to make sure I understood the information correctly😅
Also would dating this as late Edo period mean from 1800-1867 or would it it be a smaller time frame?
thanks again for all of your help, this was been very enlightening!
