Well I agree with pat and pappy, It is red elm. I presently have several staves on hand, that is what it looks like to me, However it somewhat looks like black walnut, except for the dark red hue.Then Again you would have known that for the nuts at the base of the tree. O:)I have several hhb staves and have worked with it several times. I think it is the hardest wood to build a bow from, But ooh what a beauty it is when you get one completed. By the way I fine red elm a lot like black cherry , and all the ones i built needed backed. It is a light wood, but is quite fast. A real pretty bow tho. Hhb needs no backing and i use the sap wood for looks too.I might add it seems to twist easy. My 2 cents. Denny
