Started the veneering process, it's American Black Burr Walnut.
Spent ages thinking about how the pieces would be cut from the sheet. I ended up making paper templates and laying them out on the sheet, just to make sure they would all fit butted up together, this was essential to get a continuous grain pattern over the surfaces. When it was all laid out I only had 50mm extra veneer on the length and 5mm on the width so no room for error. I found the Burr much harder to work with than ordinary Walnut, it's brittle and cracks easily.
