Sideboard Buffet

I do not know what this item is exactly called. I cannot find another to match it to. Is it a sideboard buffet or a hutch? I would like to know something of its making. I brought this from my ex husband as he needed some money. He said it was his grandmothers that she transpoirted from accross the plains when she migrated west. The beveled glass is original. I may be interested in selling this piece. I appreciate any information that anyone would give me.
