Black walnut top, purpleheart legs, and maybe a maple plywood drawer front?
Looks like the side of the casing might also be the same hardwood plywood, just stained much darker?
Those were my three guesses too. Why one would use ply or stain on something like this has me bewildered.
I could be mistaken, but many years ago I believe I learned that plywood is generally made by spinning a log while slicing a thin veneer off the surface, then stacking multiple of those veneers into plywood. The grain on the surface would be notably different when cutting wood with this method compared to sawing planks
Correct. Plywood gets a lot of strength from the alternating grain directions in each layer and the core plys aren't always the same species as the veneer/face plys.
OP specifically said not the endgrain, so just the other two, the ones that don't show their endgrain.
