Agreed with Buell, Could be sapele or any number of 'new' timbers. My opinion is that it is rotten to plane under hand or power and the grain often changes.
Coco bolo is one of those lovely woods to turn and i recall African Blackwood, Partridge wood, Kingswood and lignum vitae. African blackwood is the real thing for Northumbrian Small Pipes as well as 'half longs' of the Border bagpipes . Blackwood is now so precious that the turnings are mixed with plastic and re=machined. Ideal wood for musical instruments such as clarinets and oboes.
I had a B flat clarinet to the simple system made for the British Xylonite Co by Hawkes before they became Boosey( and Hawkes) and it was made from one of these exotics but stained to look like blackwood.
Sadly, I foolishly gave my stock of blackwood away. However probably the best information really is still "Holzapffel'
Bowls- for bowling are no longer lignum vitae but- I think Hensolite- well mine are
