This miniature is made from North American black walnut, hand-finished with five coats of Daly's Satinthane.  Every piece was cut to its precise dimensions on a router table.  Assembly and final sanding was done entirely by hand.  It is fully functional, the roll-top comes all the way down and every drawer and writing board opens and closes.

You can see an animation of the desk top and drawers opening and closing in my animation reel.
