Buffet sideboard

Possibly walnut. No veneer except on the 3 drawer fronts and it looks like burl. Original brass hardwear. 100% wood. Top is 1/2 inch thick solid plank. Has cellaret drawer in sideboard. Had a hutch at one point.  Hand carved doors and drawer front, middle 2 stick out then curve back in.... No idea of the date or origin. Help please, whats the wood and value?  Thank you
