Is it a hard wood? Easy way to tell: push into it with your thumb nail; if your nail pushes into it then its likely too soft, if it makes your nail bend then you may be ok.
Of course a good cleaning and some soaking is suggested. Test it in a tub or another large container and see if/how it changes the water parameters.
Sorry I cant ID it, maybe someone will chime in that knows what it is.
I agree that it does look quite fresh but will also admit its an awesome looking piece.
