Take a piece of the veneer, which is falling off anyhow, and compare it to the gallery on the Constantines web site, you will have to either use the unfinished side or strip the finish off the front side, to compare it properly. I think that you may be right about it being Zebrano/Zebra wood, but it could also be quarter sawn French walnut veneer cut with it's grain on the diagonal, it's hard to tell with that light walnut coloured finish they used over everything.
