Wenge is a type of wood. Obviously the maple is stained to match. The easiest way for you to match, if you are not good at finishing wood, will to be just get wenge. I had a nice resource list come out in PFM in March (I think).
The following is a cut and paste from that. Azuelas is the only one on the list to have wenge. They can chop and finish it if needed, or ship raw. Many profile available, more than likely, the one you need too.
