Hey thanks, I shall first see comes from this forum.
I am thinking in the range of: Merbau, Pyinkado, Santos Mahogany?
It has a wavy grain and also very dark redish brow colour. Well don't think it's Santos Mahogany it's not that red and hasn't got that shimmering mahogany stripes.
Maybe MUIRACATIRA or Jatoba?
Nope not MUIRACATIRA=tigerwood.
Jatoba/Merbau/Chico/Curupay (last two are most likely because of the black streaks in the wood)
Well strongly I think it is Curupay (Patagonian Rosewood)
