Momoyama or Early Edo Koshirae?

Hi all,

My new sword has interesting Koshirae that I'd appreciate your opinion on. The tsuba and menuki have what appears to be Hashiba clan kamon (5-3 kiri), while the kashira and fuchi have beautiful phoenix on them (see photos). I've been trying to find exact matches online, but of course, that's almost impossible. I'm thinking they were kokinko style from Momoyama period, but someone told me he thought they were Edo. Any thoughts?



P.S. The sword is Tensho era

The sword to which the koshirae are attached is by Fujiwara Toyomasa from Bungo province. He was actice from 1573-1592.
