Pretty much so...Euro (French, Italian, Persian, English, etc) Walnut. Not American black walnut, tho. Many veneer sources have it, some with fairly straight grain (flat cut), like the original, or more figured of the same species. I always like a little more character (see small left curved piece below) than what ours had originally, but that's just me.
Second pic is a gauge surround in French walnut, with no finish, so you can see the warm yellow-brown color.
