Pete,
I used a razor to remove part of the leather covering on the handle of the sword.
Underneath is a light colored wooden handle and a visible mekugi (Peg). I stopped there in caution.
Attached are photos of both sides of the handle with leather cover removed and a visible mekugi.
I understand that the ultimate identification will not be possible until the mekugi is removed, the handle is removed to reveal the tang.
Nevertheless, I am interested in what you think of the wooden handle and its condition and possible refining of the guesstimate of the type of sword.
