Sounds like you are pretty busy, Mate.
i'll try to get better close ups. also have a mumei, ubu katana in poor shape that Mike Virgadamo (my sayashi friend) says has the sugutha of an Uda School ca. 1560. i have my doubts, but since i know nothing....
has several kizu and an area where a small patch was welded on, i guess to cover up the shigane peaking thru. a bundle sword of some sort...but at least cared for for a few hundred years, even if it is not from the late Sengoku.
these tsuka did not come from that katana. the tsuba i posted, with the wrapped tsuka with menuki in the picture did.
later. doug e.
