I had a rosewood RWH that I got new in '63. The wood was a lot darker than that. Mine had small tips, but not built up as nicely as Chucks as I remember.
It does not look like Brazillin, East Indian, or African rosewood to me, but then I am no wood expert.
Personally, I don't care if it is walnut, or some other hardwood...that is one B-U-T-Ful bow.
